/* HINT: Search archives @ http://www.indyramp.com/masq/ before posting! */ Hi all. I read the masquerading faq but I cannot solve my problem. So I search for help within this list. I have a small LAN with dynamic IP assigning. The LAN consists of a linux router (kernel 2.2.5, Suse 6.1) and two window PCs. Standard masquerading works perfectly. Now I have to use a non standard service from Interactive Brokers (www.interacivebrokers.com). They have a special program for buying/selling contracts. Each customer gets its own UDP and TCP ports for communicatin with the IB firewall. They wrote: "The Interactive Brokers' Trader Workstation needs to establish two communication channels to IB's firewall. One of these channels uses TCP and the other one uses UDP as the underlying communication protocol. Since the UDP source and destination ports and the TCP destination port are checked for at the IB firewall, it is the customer's responsibility to set up the necessary translation services (proxies) on his/her firewall as described here. source UDP port: 59341 destination UDP port: 59379 destination TCP port; 1997-2000 destination IP address: 208.245.107.3" There TCP/IP client program tries to connect to IB with udp packets on port 59379. I see the packets arriving the router over eth0 but they are not forwarded over ippp0. I tried to use ipmasqadm without success. I did the following: ipmasqadm portfw -f ipmasqadm portfw -a -P udp -L 208.245.107.3 59379 -R 192.168.1.1 59379 No packets appear at ippp0. 192.168.1.1 is one of the local window PCs. I tried some other combinations with ipmasqadm, but all failed. I actually do not know if I can and how to setup the masquerading so that the ports will be properly forwarded. Or must I write a new module which supports these special ports?? Perhaps someone can help me setting up the masquerading to resolve the problem.
