Max MTU

[ahuebel]

I have a windows xp pro machine that I use as my internet gateway. I also have PPPoE ADSL internet access. I need to know how to lower my Max MTU to 1452 because of a known problem accessing certain web pages behind an XP Pro gateway using PPPoE. I need to change the MTU on a Redhat 8.0 machine.

I found a posting at a newsgroup on this one, apparently it's pretty easy, and if you have a Linksys 4 port router you can change the mtu there and avoid changing it in Linux or Windows. I've cut and pasted the way to do it below

In redhat, its easy, go to
/etc/sysconfig/networks
edit ifcfg-eth0 and add the line MTU=1492 (or 1454 or whatever
you want to try) and then it will work..

[Actually I think the file is in /etc/sysconfig/network-scripts.]

thank you. I dont have a linksys router (hence using my xp box as my gateway) but adding the line to my ifcfg-eth0 worked. Thanks again.
