vpn pat connection error

We have configured a vpn (over internet) between two cisco 806 and it's working.We also have configured PAT (because we have only one public ip address for each site) to access internet.

The problem is that we can access some site (like cisco, ibm or dell) but that's all.The ping or traceroute is OK for all the site but the browser is unable to load the page.

Any idea what is going on ?

Re: vpn pat connection error

Hi,

Seems like an MTU related issue to me.. try lowering that on the machine by using Dr. TCP utility and then see how it goes.

Regards,

Aamir

Thank you;It's effectivley an MTU related issue.

I just add the following line on the router config at eth1 interface (which is the pppoe interface)

ip tcp adjust-mss 1452
