Forward 192.168.3.227 to 192.168.1.133

Installing and Using OpenWrt Network and Wireless Configuration

Is this possible?

I need this because a bunch of IP Phones are contacting 192.168.1.133 (a router that has its sip ports forwarded to a laptop on 192.168.3.227) and the sip server tells them to send out voice data to 192.168.3.227

What is the topology?

Are the phones on the “WAN” side of the router, the “LAN” side? On their own VLAN? Same for the SIP server.

192.168.1.1
-----> 192.168.1.133 (router, has its own dhcp server 192.168.3.1, port forwarded SIP 5060 to .227)
-----------> 192.168.3.227 (SIP Server)
-----------> 192.168.3.129 (working phone connected to 192.168.3.227)
-----> 192.168.1.238 (phone connectd to 192.168.1.133, which then tries to connect to 192.168.3.227 and fails)

On 192.168.1.1:

  • Add a route to 192.168.3.0/24 via 192.168.1.133.
  • Make sure the lan zone forward policy is permissive.

On 192.168.1.133:

  • Disable the masquerading for wan zone.
  • Add a forwarding from wan to lan zone.
