Sonicwall WAN Interface not working
I'm trying to set up our Sonicwall NSA 2600 on a new Internet connection and I'm having trouble. Our new Internet is a Fiber connection and when I connect my laptop to the ONT (Modem that converts the Fiber to Ethernet) and I statically configure the NIC on my laptop, it works great.
However, when I statically configure the WAN Interface on the Sonicwall and plug it in, I get nothing. No DNS resolution no access, nothing. From the Sonicwall it fails when trying to communicate to the local gateway or even DNS servers.
I tested this Sonicwall at my work at a different location on a secondary backup circuit and it worked just fine. But when I bring it to this other location, I get absolutely nothing but yet my laptop works directly to the Modem with the same IP settings.
I also made sure to completely allow all traffic through the firewall just in case.
What am I missing here??

I have a setup with a static ip to my cisco asa firewall and then to my routers switches etc. The only thing I can think of in reference to my network having a similar layout is usually the modem has to be put into something called passthru or bridge mode. If this was already done then it should have just picked up and worked unless the device is trying to use a DHCP address then it might have taken some time for the modem to refresh and issue out the IP only thing I can think of since it wasn't configs. Glad to hear its working
When you change devices like that, you either have to let ISP know or wait a while.

I had the right config, just took some time to start working.
no shut to enable the interface but if this works with the laptop then the interface is up
Speed settings
Duplex auto full half
IP address dhcp static
ACL ??
NAT
is there a route to the GW from your firewall to the modem
there needs to be a static route
look at the configs of your firewall at your other site and look for a static route command like in the example below keep in mind there could be more to this as things need to be added for NAT etc
example
WAN INT 192.168.10.97 /29
modem GW static route set on firewall 0.0.0.0 0.0.0.0 GW IP 192.168.10.102/29

dns resolution has to come from either your ISP for from your inside network are you hosting dns services if so the firewall needs to be setup to allow dns requests out 53 TCP/UDP and back into the device that requested it
