Dear friend: ( I am not on the list) I've got a LAN with one linux + few win9x clients, the linux redhat 6.0, kernel 2.2.12 has one isdn to connect online frequently. Use IP-masqurade, squid, sock to get online.( i rarely thinking about the security)Nowadays, my friends on win9x are complaining about the firewall. They find a website www.dialpad.com which enable u to connect analog telephone via Web browser<it's a java applet> but remote could hear us, but we can't hear the remote voice. That because of we use ip-masq, so the udp stream didn't come to the correct win9x client through the linux. I've read help from www.dialpad.com. it want me to use ipchains to allow masq upd ports 51200-51201 and tcp ports 7175 ,51210 /usr/sbin/ipmasqadm autofw -A -v -r upd 51200 51201 -c tcp 7175 /usr/sbin/ipmasqadm autofw -A -v -r tcp 51210 51210 -c tcp 7175 but i don't know how to enable it... my ipchains settings in /etc/rc.d/rc.local //////////////ipchains -P forward DENY //////////////ipchains -A forward -s 10.0.0.0/24 -j MASQ #my pc are 10.0.0.x, and my linux is 10.0.0.1 when i run ipmasqadm autofw xxxx,, it said /////////Adding autofwd tcp ports 51210 - 51210 via tcp ctl port 7175 US /////////autofw: setsockopt failed: Invalid argument Please help me Yours Simon - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to [EMAIL PROTECTED]
