    Hi, have a look at Advanced->Conntrack/Netfilter. There is an option to adjust TTL. Maybe this is what you're looking for.

    about ttl

    Problem is that:
    My provider have a TTL restriction. All Incoming packages is with TTL=1 , and all outgoing packages is checked about TTL=128. IF TTL is differend packages is rejected. I use ttl corection +1 and all work very fine. But when i use inernal Dyndns updator this package is rejected by provider (may bi TTL is not 128 ), and Tomato report about error. If I'm not use TTL correction DynDns updator is work fine , but Internet is not routed to computer.That why I need to set TTL=128 for all autgoing packages, and use TTL +1 correction.
