Hey,
I have a query on NAT interaction for VoIP protocols. I'll attempt
some ascii art....
10.0.0.0/8
192.168.1.0/30
Internal subnet
Internal
LAN<------------------------------->Netscreen<----------------------------------->Cisco<------------------------->Partner

No the inter-agency subnet of 192.168.1.0.30 is used for link
addressing and there is agreement to use other private addressing for
services, such as VoIP... For example the subnet 192.168.100.0/24 is
used by the Netscreen and 192.168.200.0/24 for the Cisco. So on the
Cisco side they hide the SIP and RTP VoIP traffic behind a single
address of 192.168.200.100 and I need to do the same on the Netscreen
and hide the traffic behind a single IP 192.168.100.100.
I can do a MIP for the SIP proxy, as it is a one to one correlation,
but how do I hide multiple IPs behind a single IP that isnt in the
Netscreen interface subnet?
Is there a way to do a ANY to a single IP that is not in the egress
interface range?
thanks
Ivan
