HI All,
having a stange problem here..
i had a 2611 with 2 ethernet ports one for LAN and the other terminating on the ISP Internet device (radio bridge)
it worked well i has setup a tunnel to the head office and PATTED for internet acess
now we bought a 877 to replace that and made vlan1 as LAN and vlan2 as Internet
i can access the head office via tunnel 1 but the PATTING doenst seem to work any more...
from my desktop ic an ping google.com and other public ip add /names but cant seem to open any page or browse the internet
intranet pages from head office servers work fine..
is this a problem with 877 ???
what am i doing wrong ? plz help ..
thanks.

Your post suggests that it is a problem with PAT. But it also says that you can ping public addresses in the Internet. If the problem were PAT then I would expect ping to not work. And if ping does work then it suggests that the problem is not with PAT but is with something else.
I notice that on the tunnel interface you have configured this:
ip tcp adjust-mss 1400
but on VLAN 1 and 2 you have configured:
ip tcp adjust-mss 1452
I am not sure why you have done this inconsistently. I would suggest that you make the value on VLAN 1 and 2 lower and see if it helps with your problem.

Do a tracert to www.google.com.sg
don't think you are a proxy, aren't you?

no , am not.
just picked up a hint that maybe my IOS doesnt support multiple vlan routing
im using (C870-ADVSECURITYK9-M), Version 12.4(9)T7
somone suggested tat i upload an advance ip service IOS
lets hope that works.
