I need a L2 tunnel over a comercial FTTH connection that use pppoe. I have used L2TPv3 and now EoMPLS over GRE. I know that L2TPv3 can fragment the packets automatically but as I have said the performance in a NPG1 c7200 is not very good (5-10Mbps). If I configured the MTU in the host the performance is better (20-30Mbps).
In theory PMTU should work but everybody knows that ICMP packets can be filtered. So some web sites are very slow.
Now I have tried EoMPLS over GRE. The problem is the same. I need to reduce the MTU in the host. I do not know the
performance in a real c7200 .I can not increase MTU in the CORE links because is a remote site that using a comercial connection.
I can't understand why "ip tcp adjust-mss" does not work. Well I know that the xconnect is before TCP inspection so the router does not change the MSS in the TCP SYNC packet. This can not be considered as a bug but I think can be considered as a interesting feature in this scenarios (can some people cisco tell something about it?).
Finally, there is any others solutions for a L2 connection through a comercial (DSL, FTTH,...) connection without
This document gives several answers on frequently asked questions for PFRv3 channel state behavior.

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
