|Need help configuring a new router. This router will sit just inside the ISP router. It's a Sonicwall TZ 210. The primary purpose is to do content filtering. |
The current external IP address of the ISP router is 184.108.40.206. I would like this IP address to say the same, so that I don't have to change other external configurations, such as connecting with PC Anywhere.
The current gateway IP address of the ISP router is 192.168.0.20 for the internal network.
I would like the gateway IP address to stay the same, so that I don't have to change any internal configuration.
The DHCP server is the Windows 2003 server with an IP of 192.168.0.2. This is also the DNS server.
The finaly issue is that there is about 32 ports current being forwarded by the ISP router, and I need this same forwarding to work after the new router is in place.
So as I understand it, this is what I need to do:
0. Have the ISP change the External IP address of the their router to something different such as 220.127.116.11.
1. Set the external (WAN) IP address of the Sonicwall to 18.104.22.168.
2. Set the internal (LAN) IP address of the Sonicwall to 192.168.0.20 so it will be the gateway on the LAN.
3. Duplicate the current port forwarding on the ISP router on the Sonicwall.
4. Remove the port forwarding on the ISP router.
5. Connect the network work up and all should work as before, except that all internet traffic will be going through the Sonicwall before going out.
One more thing, my ISP told me a crossover cable was necessary to connect the two routers together. I thought a crossover was no longer necessary.
Thanks very much.
