Hello !

Recently i figured out i need to change TTL of all outgoing packets to
the same value eg 64. Behind bering box is NATed 3 computers network
and i need to make all outgoing traffic look like it is originating

from one machine. AFAIK this is possible by iptables packet mangling

but i can't success setting rules in bering iptables. Is it possible
with bering?


Sure, easiest way is to use Shorewall, it does it by default.


Shorewall doesn't alter the TTL of packets passing through the firewall/router and has no native support for doing so. The OP needs to insert the appropriate rules into the mangle table POSTROUTING chain to set TTL as required. The iptables commands can be placed in the /etc/shorewall/start file.
