If you did it on your routers, then you are creating or at least complementing the problem.
On the CPE dialer interface. On the ezvpn dvti virtual-template
The only way to make smaller MTUs work is to alter the MTU on both the origin and destination systems. Altering the MTU anywhere along the path only breaks things.
Lower than 1500 mtu always requires some kind of hack in real life. That would be the adjust-mss which is the hack-of-choice
