2610 pppoe problems

[Pikoro]

Fairly new to cisco equipment. Anyways, I got a 2610 set up with a NM-1FE-TX installed. FE is plugged into my "dsl modem" and E0/0 is plugged into my LAN.

Nat is running, dhcp is running, all the clients can access the internet, however, some sites just don't show up anymore. can't hit microsoft.com, ebay.com, and my company's mail server (only tested these few common sites). Other than the router, nothing else on the network has changed.

I have tried adjusting the mtu, mss, etc... same thing. Nobody on the internal network can pull their email from the corporate mail server anymore...

Can anyone give me a clue as to what might be the problem?

i added this line "ip tcp adjust-mss 1452" to all the eth and fasteth interface, and it work, did not have time to filter out which interface do not require it.


One Question, I though only nm-1e and nm-4e can be use in 2600, do you get 100MBPS for nm-1fe?

Turns out it was an easy fix. Had to add ip tcp adjust-mss 1414 and ip mtu 1454 to the Dialer1 interface.

Works like a champ now.

Yes, I have a 2610 and the NM1FE-TX shows up as Interface FastEthernet1/0

Connects at 100Mb full duplex.

interface FastEthernet1/0
description Outside Interface

no ip unreachables
