Sonicwall TZ 210 setting up a block of IPs from ISP
Posted on 2013-11-04
I am running a Sonicwall TZ 210 with SonicOS Enhanced
We have a block of IP addresses from our ISP.
One of the IP addresses are being utilized on our Sonicwall lets call it 220.127.116.11.
The other is configured on a D-Link router lets call it 18.104.22.168.
We currently have clients accessing two servers via the D-Link router. However randomly during the day our clients will lose connection even though we are still able to access the internet using the connection from the Sonicwall. The only way to resolve the problem is to power cycle the ISP's modem, but the frequency that we are having to do this has increased dramatically leading me to believe we may have some possible hardware failure involved.
As part of the troubleshooting process I have tried to get rid the D-Link and configure the Sonicwall to handle all of the traffic for both IP addresses, which I believe is the way it should have been set up originally. However, all of my attempts to make this work have failed.
I've created the services to the ports that both of the servers need, created the service groups. And have gone through the public server wizard to configure the address objects, NAT policies, and access rules but it is not working.
According to the posts I have read, once you have one WAN port configured with an IP from the block of IP addresses assigned that what I have done is all that you have to do. Do I need to get my ISP involved and have them replace the modem?
