Transporting QinQ across a Layer 2 link locked at 1518 octets AND across a Layer 3 link

Only input I can give is on EOIP tunnels and MTU.

Scenario is we had 1 remote router running, Tunneled back to our network
using EOIP so that the remote network could use our ip space. Don't
remember how I figured it out, But I was using the MTU of 1458 (On the EOIP
interface). Everything was great, But weird things started happening.
Certain sites wouldn't load, it was strange. Jacking it back
up to 1500 flat fixed it.
