Setting TOS bit in related packets

Hey all,

I'm running a Ultra-2 with Solaris 8 108528-12 and I'm trying to get this box to maintain the TOS bit in the TCP headers on related sessions.

Namely I have firewall in front of the box that is setting a TOS bit based on inbound interface however this bit is always reset on any related packets sent back from the sparc.

Anyone know what I can do/set to make the sun box maintain TOS bits across related TCP sessions? Or any software that would do this for me?

Thanks,
Evan
