MTU Issue on Cisco 1941 Router

We have Cisco 1941 router and Cisco ASA 5540 firewall. We have VPN tunnel between ASA and Router.Router is behind the firewall and the peer IP of Router is NATed. Issue we are having is we are not able to browse the sites. If we adjust the MTU size on end devices we can browse some sites but its not allowing us to change the MTU size on Router Interface.

Please suggest?

Thanks,

Prasad

Try this command on router and see if works -

(config)#crypto ipsec df-bit clear
