Hello, I have a problem whit Meessenger and i'm going crazy

I'am probing 2 MT one as gateway of the other and this giving access to my clients


Internet ------- MT Gateway------- MT Access ------- Client
Provider--------Nat-W.Proxy-------Queue-PPPoE------IP-PPPoE


If i use a fixed IP everithing works fine but the Messenger couldn't connect

I could connect Messenger but only if i dial via PPPoE

Anyone have this problem before o I'm doing something wrong ???

Thank you and excuse my english

bye

The problem was in the MTU of the interface

The MTU was in 1480 and I couln't connect the MSN Messenger but if I put it in 1500 the Messenger goes fine

Then I put the LAN interface in 1480 and the WAN in 1500

It's all rigth ??? or I have to set booth interfaces in 1480 ?????

Thanks
