Greetings!
I would greatly appreciate any advice I can get. I've configured a
Dachstein firewall for my network and I've got a pretty good handle on
the firewall rules, but the port forwarding stuff has got me stumped.
I've been assigned a block of 16 IP addresses in addition to the primary
IP of my firewall. I would like to forward pcAnywhere traffic (which is
TCP port 5631 and UDP port 5632) to my internal workstations. I've set
up the EXTERN_IP as the primary IP x.x.x.231. I set up
eth0_IP_EXTRA_ADDRS with the 16 additional IP's.
I would love to be able to have a client attempt to "Connect to remote"
in pcAnywhere using one of my additional IP's (e.g. x.x.x.50) and have
that port forwarded to the workstation with the internal IP
192.168.10.50 (the workstation is configured to "Wait for a connection"
in pcAnywhere). If the client attempts to connect to another of the
IP's, the request would be forwarded to the appropriate workstation.
I opened the ports in the firewall rules with:
EXTERN_TCP_PORTS="0/0_5631"
EXTERN_UDP_PORTS="0/0_domain 0/0_bootpc 0/0_5632"
And I then set up the port forwarding servers by adding the lines:
INTERN_SERVERS="tcp_x.x.x.50_5631_192.168.10.50_5631
udp_x.x.x.50_5632_192.168.10.50_5632 /
tcp_x.x.x.51_5631_192.168.10.51_5631
udp_x.x.x.51_5632_192.168.10.51_5632 /
tcp_x.x.x.52_5631_192.168.10.52_5631
udp_x.x.x.52_5632_192.168.10.52_5632 /
tcp_x.x.x.53_5631_192.168.10.53_5631
udp_x.x.x.53_5632_192.168.10.53_5632 /
tcp_x.x.x.54_5631_192.168.10.54_5631
udp_x.x.x.54_5632_192.168.10.54_5632 ..."
However, this still does not allow clients to connect to my internal
boxes using pcAnywhere. I don't need to allow any additional traffic
through on my additional IP's. Am I missing something here? Have I
misinterpreted how the Intern_servers work? Any help would be most
welcome!
Thanks,
Ken Marshall
