Hello, I've got a program for Internet telephony named SpeekFreely. While it does work on stand-alone machine connected to the ISP, it doesn't work properly when I trying to connect to a foreing host (host F) from a host inside the masqueraded network (host M). 1. M calls F - I get a connection, but the sound flows only in one direction - from B to A. 2. F calls M - nothing happens on B. It seems to be working the 2072 UDP (and may be TCP) port. I've tried to configure port forwarding and fwmark-forwarding, I've read the man's and HOWTO's, but with the same result :( Here is my firewall ruleset (without any tricks with portfw and mfw): myhost# ipchains -L Chain input (policy ACCEPT): Chain forward (policy DENY): target prot opt source destination ports MASQ all --------- localnet/24 anywhere n/a Chain output (policy ACCEPT): I wold be very grateful to anyone who can give an example of _working_ ruleset for firewall/masquerading that allows direct connections between foreign and masqueraded hosts. Best regards, Kostya
