In my lan I have installed squid server in mandriva 2009 its working fine but I have a IP cam for video recording at remote site of a online exam. I have allotted IP address for this cam. Now I need port forwarding for that IP at 10001 port in mandriva 2009. I have done it at router but I want to do it in my linux server.
View 14 RepliesI have just set up shorewall on my router running Arch Linux. The external network is on eth0 and the internal network on eth1.I have set it up for masquerading and that works fine and I can open ports to the firewall. But I'm having trouble with port forwarding to my internal machines.The problem I have is that when port 22350 is forwarded to 192.168.1.3 on my local network, checking the port with nmap from a remote computer gives me:
Code:
PORT STATE SERVICE
22350/tcp closed unknown

I have a ubuntu 9.10 on my desktop in my office and I have another ubuntu on my home desktop. Both machines are behind a router. I guess many people have already asked the same question: how to remote control the office desktop from my home desktop?Many posts discussed about solving this by setting up ssh and port forwarding. But my situation is that I cannot control the router in my office so I cannot set up any port forwarding for my office desktop. So I guess my question becomes how to remote control my office desktop without setting up any port forwarding on the office router.
View 3 Replies View RelatedI currently use a commercial VPN when working overseas for secure internet access.
I now also need to VNC to a home ubuntu desktop (which runs software 24/7 that I need to periodically check).
When overseas, I use a Ubuntu laptop and an Android tablet.
For the VNC I intend to use an SSH tunnel. So my question is: should I ALSO set up openVPN on the home computer (so I can stop paying for a commercial provider which routes all my traffic twice across the Atlantic...) or is it easier/better to use the SSH tunnel for the secure webbrowsing too? Something like a SOCKS proxy?
We have one linux machine in the office which happens to be an important firewall. I just know the basics and need to make one changeEssentially it is forward mysql traffic to another internal machine.This is the original rule (forward to 192.20.0.17) which is working

I want to port forward port 445 to a machine on one of the LAN interfaces. I have tried various ways to get it done, but still cannot access that port from the interface. I definately know device hosting port 445 is live, as I can ping it from the CentOS box and use lynx to access it! (It's a web server)

I have two PC's, one with slackware and one with arch, and I am trying to access the web server from the archlinux machine but i haven't manage to do that. The archlinux machine is connect to the internet via the slackware machine via a crossover cable:
internet > eth0 (pc1) and ppp0 (the PPPoE connection, pc1) > eth1 (pc1) > eth0 (pc2)
PC1:
ifconfig eth1 192.168.0.1 netmask 255.255.255.0
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -i ppp0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o ppp0 -j ACCEPT
pc2:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
ifconfig eth0 up
route add default gw 192.168.0.1 eth0
/etc/resolv.conf (The same DNS as the first PC)
And now the internet is working and on the archlinux machine, but I am not able to access the web server from LAN with a public IP. I tried many iptables port forwarding commands but none worked.
I have the wake on lan option enabled on my debian computer. If i wake it by sending:
-mac adres
-internal ip in my home network
-subnetmask
-port 7
It all works fine, but when i try to do it from outside my network and change the ip address to the router adress it wont go on. I have also opened the port 7 in my router.
I have a server running debian squeeze and kvm to virtualize a Windoze box. It's setup to use NAT. This is because of limits on the network by the admin and unfortunately, there isn't a way to get around this.

View 2 Replies View RelatedI have a question regarding port forwarding. I have a fedora server, with two eth cards: eth0 ---> external IP, eth1 ----> LAN IP I use SNAT for connection sharing. I also have an internet domain hosted on this server... let's call it [URL] Anyway, one of our computers in the LAN has some kind of web server on it, which must be accessed from the internet on the port 23700.
So, using iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 23700 -j DNAT --to 192.168.1.25 (the IP of the network computer) Everything works perfectly fine from outside the lan. When I type [URL], I connect to that computer. My problem is that inside the lan, typing [URL] does not work! It only works if I enter it by IP 192.168.1.25:23700 Is there any way to make the server forward my request to that specific computer even if I'm inside the LAN?
I am running Fedora Core 10 and KDE 4.2.1. My KTorrent is having trouble finding online peers lately. I suspect this is a port forwarding issue. I have set up my router to forward port 4444 (UDP) and port 56000 and more (TCP) to my machine's IP address. I have also set my local firewall (system-config-firewall) to allow these ports through.But when I try to test ports 4444 and 56000 via this Open Port Check Tool, it tells me they are closed
View 6 Replies View RelatedI'm trying to implement remote NFS in our network
So I read a lot of posts on the Internet, but I don't understand which ports I have
to open/forward for this.
On some posts I see a lot of ports, I don't want to do this.
If this is the case, and I would set up NFS through an ssh tunnel, then do I only need the ssh port and does this mean it will always work if the server is reachable through ssh?
Or is this wishful thinking ?
I have a script to establish a reverse tunnel with other machine,My problem is to stop the tunnel. If I just kill the PID at sshtunnel.pids, ssh does not release the ports at the server side, so any new connection will fail for several minutes.Is there any way to signal SSH to exit gracefully?
View 5 Replies View RelatedThis should be easy but for some reason its not working. I don't have admin rights on one of my local networks to open the firewall for port 80 to make my server accessible remotely (from the internet). I have a remote server (OpenVZ VPS) and I want to port forward so that [url]:8080 will point to my localhost:80 from the internet itself (i can get it to work on the remote VPS server's local network)...
How could I accomplish this? Basically, I am trying to serve webpages from behind a firewall using a VPS as a hub.
would it be possible for anyone to give me step-by-step instructions on how to set up port forwarding on my laptop? I've been using Karmic Koala and just upgraded to Lucid Lynx and not really bothered to port-forward before, so not too sure where to start - googling gives me a lot of terms I don't understand.
