I've done apt-get purge network-manager, because something is screwing up the routing...
I have a dynamic IP address through Spectrum cable and I'm thinking that I need to do something special to make masquerading with a dynamic ip work? The firewall needs to track the IP if say the lease expires and I get a different one... Zoom video conferencing is not working through my Debian firewall. Maybe I'm not allowing all the packets to get through... The video freezes and stays frozen. I suspect UDP isn't getting through. Thing is, why would a forward packet be from the outside interface out the outside interface with the destination IP address being local? I don't think this is supposed to happen. FORWARD will drop: IN=eth2 OUT=eth2 SRC=172.217.6.10 DST=192.168.254.32 PROTO=TCP SPT=443 DPT=49681 ... The above seems like something that should be dropped because RFC1918 addresses aren't reached via the Internet side interface which eth2 is. # ip route list default via 96.42.208.1 dev eth2 default via 192.168.254.1 dev eth0 proto dhcp <- WRONG src 192.168.254.52 metric 202 default via 96.42.212.1 dev eth2 proto dhcp src 96.42.214.23 metric 204 mtu 1500 96.42.208.0/22 dev eth2 proto kernel scope link src 96.42.210.76 96.42.212.0/22 dev eth2 proto dhcp scope link src 96.42.214.23 metric 204 mtu 1500 192.168.253.0/24 dev eth1 proto kernel scope link src 192.168.253.1 linkdown 192.168.254.0/24 dev eth0 proto dhcp <- WRONG scope link src 192.168.254.52 <- WEIRD metric 202 michael@filter:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

The interfaces eth0 and eth1 should be static configured. The eth2 interface is hooked to the cable modem. _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
