ok, so this is my situation
I am using slackware 12.0 w/ asterisk 1.4.11 so this is my rc.firewall script:
[code]echo 1 > /proc/sys/net/ipv4/ip_forward
iptables --flush
iptables --table nat --flush
iptables --delete-chain
iptables --table nat --delete-chain
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT
iptables -t mangle -N common
iptables -t mangle -N asterisk
iptables -t mangle -A common -p tcp --dport 80 -j MARK --set-mark 2
iptables -t mangle -A common -p tcp --dport 8080 -j MARK --set-mark 2
iptables -t mangle -A common -p tcp --dport 443 -j MARK --set-mark 2

iptables -t mangle -A FORWARD -i eth0 -o eth1 -j MARK --set-mark 3
iptables -t mangle -A FORWARD -i eth0 -o eth1 -j common
iptables -t mangle -A FORWARD -i eth0 -o eth1 -j asterisk
iptables -t mangle -A FORWARD -i eth0 -o eth1 -p icmp -j MARK --set-mark 1
[/code]
this should be creating some qos for my SIP and other stuff for asterisk.
My phones are on private nat lan behind this box:
eth0 public
eth1 private
I have another asterisk box at work and need 2 of my cisco 7960g phones to be able to connect there… I can connect, but calls from the office box do not make it to my home phones behind my home asterisk box, and my home box looses connections with my voip devices on my lan here. I’m hoping that changing some ports my fix the issue with the remote box, but not sure how to do that. For example, if I was to change sip from 5060 to 5061 and rtp from 10000-20000 to 25000-35000 how could I fwd those ports to more than one location on private network ie.{(10.77.76.41 and 10.77.76.42)or even to a range of ips}?? in iptables is there seems to be no pnp, am I even going about this right?? Should I peer the asterisk boxes so my work queue rings through to my home box… if so, how do I peer in SIP?
any advise would be greatly appreciated…
Kind Regards
