[SOLVED] SSH Connections
Hello,
I have a laptop running off a wireless connection to the router and a desktop PC running off a USB/Ethernet connection to the router. I have OpenSSH installed on both machines. How do I sort port forwarding correctly? The local machine IP's keep changing.
Thanks.

Re: [SOLVED] SSH Connections
either:
set static ip for your machine
or:
write a script that ssh's into the router and changes the iptables rules
first one will be 10x easier

Re: [SOLVED] SSH Connections
I read the Wiki however I'm still not sure I understand this. I'm currently using DHCP.

Re: [SOLVED] SSH Connections
Check your router's dhcp config, usually there is some way to assign IPs by MAC-Adress.

Re: [SOLVED] SSH Connections

You should put lines that look something like:
eth0="eth0 192.168.1.101 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(eth0)
...
gateway="default gw 192.168.1.1"
ROUTES=(gateway)In your rc.conf... with the correct values for your network of course.
I haven't lost my mind; I have a tape back-up somewhere.

Re: [SOLVED] SSH Connections
As Garns above says, most routers allow you to assign IPs depending on the MAC Address.
This will let you keep DHCP, which is important if you are mobile.
You can find the MAC Address for example with 'ifconfig'.
My router, an ASUS 500gp, on the DHCP configuration tab has an option 'assign IP manually', in fact a
table with 'MAC --> IP' assignments.
Look for a similar option on your router configuration.
