路由问题，带有通过FusionPBX运行Debian Jessie的LAN和WAN端口的服务器

Question

I am trying to wrap up a FusionPBX install on Jessie. The network for this company is not what im used to.

The server has two Ethernet ports, one is LAN the other is WAN. I am running iptables, fail2ban(both setup by the Fusion PBX script, however I have been trying my own iptables chains from the working server this will replace). The sever I am replacing is setup the exact same far as networking and iptables.

On the new sever when I try to have my phones register to the new server they fail if my network config is like I have posted below. They will register when I change the default gate way to 192.168.0.1 on eth0. However when that happens I get one way audio, since the calls come in the wan(eth1) and try to exit via eth0(default gateway).

When I change the default gateway to be on the WAN and use interface eth1 the calls have 2 way audio, but the phones will not register via the LAN.

I am used to servers typically having either a wan or a lan but not both. Do I just need 2 default routes? Any insight would be a great big help.

The primary network interface

allow-hotplug eth0
auto eth0
iface eth0 inet static

address 192.168.0.45
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
####gateway 192.168.0.1
dns-nameservers 192.168.0.1
dns-search mydomain.com

WAN interface

allow-hotplug eth1
auto eth1
iface eth1 inet static

address 172.217.3.174
netmask 255.255.255.252
network 172.217.3.172
broadcast 172.217.3.175  
gateway 172.217.3.173

Answer 1

Each SIP profile in FreeSWITCH binds to one IP address and port. You need to control that, and probably you need multiple profiles, as you have two NICs. I don't know how it's controlled in Fusionpbx, but there should be settings about that.

Answer 2

如果要在服务器上注册多个接口，则需要在freeswitch中具有多个接口的多个配置文件。
