Re: PCAnywhere and IPCHAINS
Hello nate,
The PCAnywhere Host has the FW server as the default gateway.
I have installed TDIMon, no traffic going to server P when I executed
PCAnywhere at external client PC.
One question, must it be NAT, i.e. extra external IP required? What I'm
trying to achieve is port forwarding only.
pc C (x.x.x.b) -> server FW (x.x.x.a, 192.168.1.1) -> server PCAnywhere Host
(192.168.1.2)
Route table on PCAnywhere Host:

From server FW, I can telnet to PCAnywhere Host's port 5631. But from the
TDIMon, I see
connection from internal IP, i.e. 192.168.1.1.
Should I allow connection like external IP to internal interface for PCAnywhere
Host's IP? Even
though I already done the portfw configuration?
Thanks.
Regards,
Simon.
