route misconfiguration

[bushwacker]

Hi. I was reading a tcp/ip performance tip on speedcorp.net which suggested that the MTU, Rwin, etc. of a connection could be modified using the route command:

route add -net 192.168.0.0 netmask 255.255.255.0 dev eth0 window 65535 mss 1460

However, When I did this, the gateway clients on my LAN lost all connectivity to the Internet through my server except for a few programs such as MSN Instant Messanger, which is really strange considering a PING couldn't even reach the screwed up server. My exact route input was:

route add -net 192.168.0.0 netmask 255.255.255.0 dev eth0 window 65535 mss 1500

My question is this: How do I remove a bad route entry from my server route config? the internal LAN connects to eth1 on my machine, and I put eth0 as the route by accident, which may be causing the problem.

Use route del

This may sound utterly stupid, but what's the syntax for this (in detail)? Im just starting the IT/networking bit with linux, and I've never used route much (if at all) before. Thanks in advance.

I'm pretty sure it's the same as the syntax for add.. the man page might help.

This is insane. I dont want to admit it, but is there a graphical way to do this? IM realy confused here.
Thanks in advance.

open up a command prompt and type this:
route del -net 192.168.0.0 netmask 255.255.255.0 dev eth0 window 65535 mss 1500

Now that that got out of the way, I was able to continue the system security procedure with Bastille Linux. Thanks for the help.
