connect 2 routers together using one as a SIP device
I have a network which works fine using a Juniper 5GT router.
Recently, I came into possession of a Belkin VOIP router with a VOIP account. I'd like to know if there is a way I can continue using the Juniper as my main router, and connect the Belkin on the LAN just to be used for VOIP (single handset).
Le'ts call the Juniper ROUTER A and the Belkin ROUTER B herein.
I've connected PORT 1 from ROUTER A to PORT 1 of ROUTER B and set ROUTER B to use an IP in the same subnet i.e. A = 192.168.102.1 B = 192.168.102.253.
On any PC connected to ROUTER B I can gain internet access. ROUTER B can see and PING ROUTER A.
Unfortunately, ROUTER B cannot ping out from itself to the www. Therefore, the SIP device never connects.
If this isn't possible then thats cool, i'd just prefer to make use of this device and avoid buying a seperate SIP device.
Thanks for your help and ideas!!

Hi thanks for your answer
I mean port 1 as in, both devices are 4 port routers. The Juniper has a WAN port which runs into a run of the mill ADSL modem.
The Belkin however, is an ADSL router with 4 LAN ports (no WAN) and therein lies my difficulty in configuring.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
BUT, presuming the Juniper box has its WAN connection to your ISP, you should be able to take a LAN connection from the Juniper router and connect it to the WAN side of the Belkin box. This gives the belkin a WAN IP of something like 192.168.102.X then on the LAN side of the Belkin box, if you plug in a computer you should get an IP in a different subnet.
esenttially performing NAT twice.
now, you'll also probably need to setup some rules on the Juniper box so that the Belkin router either has the necessary signalling and RTP ports forwarded to it, or so that the WAN IP of the Belkin router (which is on the LAN side of the Juniper router) sits in a DMZ.
VoIP TCP/UDP/RTP ports will vary depending on the protocols used and provider.
