/* HINT: Search archives @ http://www.indyramp.com/masq/ before posting! */ Hi all! I have a problem with my ip-masqueraded LAN. A linux router (kernel 2.2.11) is used for NAT and masquerading because I only get one IP address. Now the problem: On one PC in my LAN a special TCP/IP-Client is running which is using UDP ports for sending at 57881 and receiving 58313 and TCP ports 1621-1623. The server for the client program with the IP-Number 111.222.333.444 waits to receive unmasqueraded packets and then sends the UPD packets at the specific port. What I have to do is to route the UDP port numbers 58313 & 57881 and TCP Ports 1621-1623 directly from the one PC to the 111.222.333.444 server over my linux router. I tried ipmasqadm without success. If my configuration is as following: linux router (ippp0) : 192.168.0.90 (Inet, dynamically assigned IP) linux router (eth0): 192.168.1.10 (LAN) No firewall rules are enabled, only masquerading and network address translation. PC: 192.168.1.11 external Inet server 111.222.333.444 how can I redirect the above ports through my linux router so that the machine 111.222.333.444 gets no masqueraded packets and the packets are correct forwarded? After starting the client program on the PC, ipchains -L -M shows the masqueraded packets (but there is no response from the server 111.222.333.444). (clyde.berlin.de = 192.168.1.11, gw1.ibllc.com = 111.222.333.444) TCP 00:41.82 clyde.berlin.de gw1.ibllc.com 1623 (61396) -> 1997 TCP 01:41.63 clyde.berlin.de gw1.ibllc.com 1622 (61395) -> 1997 TCP 01:41.09 clyde.berlin.de gw1.ibllc.com 1621 (61394) -> 1997 UDP 04:53.05 clyde.berlin.de gw1.ibllc.com 58313 (61398) -> 57881 6 TCP 00:41.82 clyde.berlin.de gw1.ibllc.com 1623 (61396) -> 1997 TCP 01:41.63 clyde.berlin.de gw1.ibllc.com 1622 (61395) -> 1997 TCP 01:41.09 clyde.berlin.de gw1.ibllc.com 1621 (61394) -> 1997 UDP 04:53.05 clyde.berlin.de gw1.ibllc.com 58313 (61398) -> 57881 T Please help me. I'm searching for a solution for above 3 weeks without success!
