Hi all,
I'm implementing a 2 Arelnet VoIP boxes, one situated in a NAT-ed
environment with ipfilter (lets call this box N), and the other not behind
any firewall (box O). No incoming/outgoing restrictions are specified in
the firewall which is linked to box N.
A simple topology diagram:
box O ---------- Public network ---------- FW -- box N
FW's ipfilter version:
- ipf: IP Filter: v3.4.14 (264)
- Kernel: IP Filter: v3.4.8
Calls can be established. However, the calls get terminated exactly after
a minute. I modified the following parameters to the the stated values
with sysctl:
net.inet.ipf.fr_tcpidletimeout: 1800
net.inet.ipf.fr_tcptimeout: 1800
net.inet.ipf.fr_udptimeout: 1800
net.inet.ipf.fr_icmptimeout: 600
Calls still drop. I'm clueless. Any hints, guys?
Regards,
