Hi, all. Sorry for posting to this thread but I can't find any topic for DVG-5402SP router. At the same time it is similar to DVG-5102S, so I hope somebody will be able to help me.
Configuration:
There is a DVG-5402SP router with a common fixed phone connected to it. Router is connected to the local network via its LAN port and is configured to use ip 192.168.203.253. In the Internet Setup tab DHCP option is marked by default as the way to obtain ip address for WAN port.
The router is used to connect fixed phone to IMS network. When registering in the IMS network (the router is configured to use proxy server with ip 192.168.203.254:4060, it's not a mistake, we have proxy configured to use 4060 port) router sends the following SIP message from its 192.168.203.253 ip address:
REGISTER sip:192.168.203.254:4060 SIP/2.0
Via: SIP/2.0/UDP 192.168.203.184:2490;branch=z9hG4bKd4d4c334e7f856a0

You can see that "Via" and "Contact" headers contain 192.168.203.184 ip address instead of the 192.168.203.253 ip of the LAN port. I suppose it's an ip address obtained by the router for the WAN port via DHCP..but we have no equipment connected to WAN port.
Because of such behaviour registration fails. Could you please explain me such strange behaviour of the router? What should I do to solve this problem?
Thanks in advance
