Workstation (public)
(A) runs the IP filter with NAT and has public address
and B and C have private IP addresses.
Workstation wants send a packet (udp/tcp) to B. It
does this by sending a packet to A with a preallocated
port nunber for B. Does A map source IP (workstation
address) and port numbers in the packet before sending
it to B, since B does not know how to reach the
workstation. If so, does this happen automatically or
do I need configure something in the rules file?
Any help is greatly appreciated.
Cheers,
Vinay
