Help...need to replace router in front of a Sonic Wall
Posted on 2008-10-30
This week my main BT router failed. This was a managed service at one time and i can't find any documentation about its configuration. The problem i have is that it sits between BT and a Sonic Wall firewall. The sonic has been configured with two internal networks (LAN and DMZ) ports being utilized.
I have just recieced a replacement router from BT, but its unconfigured and a completely different model.
I tried to re-configure the new router and could not get my network backonline, so i was wondering if you guys could give me some advice and how to re-configure the new router.
Some documentation i have is listed below
I have a non NAT service and the range assigned to me is:
126.96.36.199 to 188.8.131.52
Firewall External Ethernet address 184.108.40.206
Firewall Internal Ethernet address 10.20.128.1
Firewall Internal Ethernet address 10.20.130.1
Firewall NAT entries 0
I also have been using windows VPN (pptp) to the following address for server1 and server2
Server 1 VPN dial address 220.127.116.11 (internal network 10.20.128.1)
Server 2 VPN dial address 18.104.22.168 (internal network 10.20.130.1)
The Sonicwall WAN interface show this configuration:
22.214.171.124 (default gateway)
So i plugged in my new BT wireless HUB unit and went to set up the internet connection and just can't get it to work. I know the internet connection is good because if i use DHCP to get an address i do. Trouble is i need to set this with manual addreses the way the old router was in order to get things up and running again.
Would really appreciate any advice on this one..
