Server :: If Forward A Port In Iptables, Does The Port Have To Be Open On The Firewall
Aug 5, 2009If I forward port 80 to port 3128 for squid with an iptable rule, does port 3128 have to be open on the firewall or is this all routed behind the firewall?

Jan 26, 2010I am trying to make a vnc connection from pc #2 to pc #1. Pc #1 is a debian pc behind a zyxel router (P-2602HW-D1A). Pc #2 is a windows xp pc another place at the internet.I have configured the zyxel router to forward incomming trafic on port 5902 to the local ip-adress of the debian box. The debian box is running a vnc server, listening on port 5902.But i dosn?t work.I have tryed to scan the zyxel routers ipadress on port 5902 from the internet, but the scanner says that the port is closed.The vnc server on pc #1 is working fine on the local network. I can connect to the server from a pc on the same side of the zyxel router.Is it deffenitly a router problem, or could it have something to do with debians own firewall?

Apr 4, 2011I'm trying to use iptables in order to forward all the incoming packets for port 5555 to port 5556 on the same server (192.168.2.101).
I wrote the following commands:
iptables -A PREROUTING -t nat -i any -p tcp --dport 5555 -j DNAT --to 192.168.2.101:5556

Networking :: Iptables Can't Port Forward (PAT Port Address Translation)?
Feb 20, 2010I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
iptables -t nat -A PREROUTING -p tcp -i eth1 -d (WANIP) --dport 21 -j DNAT --to 192.168.1.2:21
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..
Here i my iptables script:
#flush table
iptables -F
#input regler

Nov 23, 2010I have just set up the transmission bittorrent client on my server (using the web interface), and am trying to get the port forwarding right. After noticing low download speeds (and rare uploading), I decided to check if a port needed to be forwarded.
I found many conflicting sites, mentioning both the ranges 6881-6999 and the port 51413 (as well as TCP and UDP versus just TCP). My current configuration is to forward TCP and UDP port 51413 to my server.

Sep 8, 2010I have linux server setup on a network with 2 interfaces. One (eth0) is connected to the regular network and the other (eth1) has a DHCP server and transparent web cache listening on it. The machines connected on the eth1 side are on a different subnet and the linux server is there gateway. Untrusted machines are introduced to this network to keep them isolated.
This isolation works well, too well. There are a small set of resources on the regular network I would like to make available to machines on untrustworthy network. I think I need to use iptables but alas I've had no luck in piecing together the command I need (in one case looking myself out and having to physically reset the machine).

Ubuntu Servers :: Forward Traffic From A Domain To Another Server Behind A Firewall
Jan 29, 2010I have a server on my router on the DMZ. All outside traffic goes to it. This server has Apache running and the domain mysite.com resolves to the the DMZ web server. I have a second server on the LAN that also has apache running. I want to set up another domain, myothersite.com to resolve to the second server on the LAN. Since the main server is on DMZ I have the DNS A records for myothersite.com pointing to the public IP that the DMZ is on.
How do I get myothersite.com to resolve to the second webserver on the LAN? What configuration do I need to do on my DMZ server so it routes traffic for myothersite.com to the other server on teh LAN? Do I use BIND DNS? If so please advise on how to set that up. BIND DNS seems confusing and I having trouble knowing how to configuring it. Is there another option besides BIND?

View 3 Replies View RelatedUbuntu Servers :: Apache2 SSL Forward To Another Port?
Dec 1, 2010I have an apache2 server on a Debian box that I am using as the reverse proxy for my sites that are sitting behind it and everyone is happy. But now I want to be able to access my vmware server console from outside the network without exposing the vmware server port to the internet. So I did this I created a new virtual host for apache and it looks like this (edited for the real world)
Code:
<VirtualHost *:80>
ServerName server.my.domain
# RewriteLog "/var/log/apache2/rewrite.log"
# RewriteLogLevel 9
[Code]....
So here is what I want to be able to do. I want to be able to punch in [URL] and have the reverse proxy just take care of everything else without having to punch in the port number or anything else. I'd also like to have if possible the ssl on the vmware box just pass through the proxy back to the end user. If that isn't possible and I need to create a new ssl for the apache box then that is ok too. I have googled this and looked at several other sites but I'm still a little bit lost.
Ubuntu Networking :: Firewall Settings : Unable To Configure For Apt-get And Dns?

The only way I get it to work is to accept everything in iptables.

Apr 22, 2011I have a home network with a linux dhcp server and a couple of clients. The Internet comes from a dsl modem with a different subnet than my wireless router. The network works fine and I have no problems, but I now need to ssh to a work computer and the only way I can do that is if I drop the security in my dsl modem. So I thought all I need to do is use port forwarding on my dsl modem, but it won't let me because it is on a different subnet. I tried putting the dsl modem on the same subnet, but that did not work and made it so I could not access anything.

Ubuntu :: Transmission Port Forward / Internet Slowed Down
May 16, 2010While I have Transmission running, whether it be up/downloading or just open with one thing unpaused and no activity, all other computer functions that need internet access are unusable. Transmission says my port is closed in its preferences.
1. How do I find and open port?
2. Will finding an open port solve the problem of all things internet not working while Transmission is?
3. Do I need to create a static ip in order to forward a port through my router?
4. Will creating a static ip and forwarding that port solve my problem of only being able to use the internet while Transmission is on?
General :: Setup A Port Forward From Client Computer's Shell?
Mar 24, 2011I notice that my bittorrent client is capable of automatically setting up port forwards with my router, and I want to know if I can do the same in a shell script. The reason is, that since my router is stupid and won't let me keep static IP addresses (it seems they forced a DHCP refresh every week to make me want to pay for a more expensive model which doesn't), I need to get my computer to change the port forward to follow my computer's changing internal network IP address. I have a couple of port forward manually entered into my router settings for web interfaces to bittorrent etc, but of course these have a good chance of being invalidated at each DHCP refresh cycle.
View 1 Replies View RelatedGeneral :: Forward Port For IP-Based Virtual Host To Work?
Mar 22, 2010Having trouble visualising how IP-Based Virtual Host (with SSL) would work. Here is my vhosts.conf file:
Code:
#Define Name Virtal Host
NameVirtualHost 10.10.0.54:80
#Used to replace the main server host. The log file will reside in /var/log/httpd/error_log
[Code]....
How will it work? I will need to forward port 443 to the 10.10.0.55 interface right? Without doing that, there is no way this is going to work... is there? And that means that I can't run more than 1 ip-based SSL virtual host on one machine because I can't forward 443 to two different interfaces.
Also, do I use internal ip address or external ip address in the <VirtualHost > tag? I only have one static public ip.
Ubuntu Installation :: 10.04 Install :1st SATA Port Not Recognized As /dev/sda - Solve This?
May 2, 2010My computer has 2 HDDs attached to 1st and 2nd SATA ports of my mobo respectively, the 1st SATA drive is empty while the 2nd have my Windows Vista on it. I also have a Perc/5i RAID card with 2 RAID arrays defined.
I am going to install Ubuntu 10.04 x64 to the 1st SATA driver (I expect it will be /dev/sda), but when I try to install, I found my drives are recognized as below,
/dev/sda > 1st RAID array of my Perc/5i
/dev/sdb > 2nd RAID array of my Perc/5i
/dev/sdc > 1st SATA drive < I need to install ubuntu on this drive
/dev/sdd > 2nd SATA drive
I don't want to install 10.04 as /dev/sdc because I may add more arrays to my raid card which from my experience of 9.04, it will probably change the drive letter of my current /dev/sdc and then system will fail to boot.
Is there any way to force my 1st SATA HDD as /dev/sda during install ?
Fedora Servers :: Port Forward On The Fly Or At Startup With Virt Machine Manager And Kvm-qemu?
Jan 6, 2010I'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly. Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions.[URL]
As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &
