Ive read that MTU is at layer 2 within the ICMP code. It is an extension. A sub type. I know for sure that it is at layer 2 but as for ICMP being the right library to use a filter on is another question. Any one know how to create your own filters at this level?

I'm trying to implement a filter for MTU value 1522. Juniper and others do this. Stop all MTU traffic at this value.
Firewall->
filter->
filter-name->
MTU->
1522->
and so on....
I will check out that link if it applies. I was under the impression that ebtables was out of date and that dd-wrt didn't use it any more. But I am assuming.
