Hi, is anyone else having weird problems talking to raptor firewalls. What is happening is that we are running netscreen firewalls (hardware appliances) and we can't talk to any raptor firewall with its syn flood protection on. As what that does is break the 3 way handshake for tcp connections (it responds to a SYN with a ACK and a incorrect acknoledgement number). It(raptor) only behaves this way with the netscreen box, not with my RH box sitting out in the wild. ( i have packet dumps of the traffic) (i haven't had a chance to observe how it deals with PIX and checkpoint.) Is that traffic pattern an addition to the TCP standard or is it completly non standard coms. (I found rfc 0793/ STD0007 that defines what i expect, but i can't see any additions to the standard supporting the Axent/Symantic way). Anyone got any thoughts?
