I'm running a sonicwall pro vx. it's in NAT mode, and my company LAN is sitting behind it on a 172.16.x.x address range. I've got about half a dozen servers and devices on the WAN link (not counting the routers) and just one machine in the DMZ at the moment. The sonicwall is programmed with the IP's in the WAN switch, and also is programmed for the one in the DMZ. There are no IP conflicts that I can find. But randomly, sometimes two or three times in an hour, sometimes a week between, it simply locks up. No outbound traffic works, can't open the admin web page on the sonicwall, nothing. And the only way to fix it is to power it off, then power it back on again.
I'm running firmware 6.3.1.0, but it also did this with 6.2 as well a couple of times. One of the reasons I upgraded the firmware was in hopes that this problem would be cleared up.
There's no VPN usage when it happens, as I'm the only one setup at the moment to VPN through it until I can figure out a way for the rest of my clients to pull a WINS server address from their VPN connection using the 8.0 client software, since I don't want to have a bunch of lmhost files to have to maintain on everyone's notebooks.
When it happens, I can't even see if there are any errors in the log because the logs are empty. I've turned the device off momentarily and did a scan of my internal network to see if someone had hard coded the same IP onto one of their computers or something, but there are no address conflicts with it.
Has anyone else ever seen this? If so, did you ever resolve it? I still have support through September on it, and contacted Sonicwall on the 17th, but have gotten absolutely nothing from them as of yet.
Thanks for any replies.
John
