sonic wall firewall/limited connectivity?

[hubenshtein1]

ive got sonic wall firewall, 50 user, and ive got 2 pc on th network that cannot hit the internet. this network runsk nt4 dhcp and a few other services, but while these pc's cannot get onto the net they can still ping everything locally on the network, ie dhcp server and other clients. Its only these 2 clients that see the issue, tried new nics, new cable, new switch ports, and a new os load. any suggestions?

You say you have a 50 user license on the sonic wall, how many PC's are actually connected to it?

Have you verified that the machines are recieving the DHCP lease. Pull up a command prompt and do an IPCONFIG. Are the settings correct?

One thing to try is to hard code in the gateway, a valid IP address, and the DNS servers and see where that gets you.

yea, we've tried that, the machine itself can still see the rest of the internal network, and we did renew the lease, and these 2 pc's will see the net for a breif period of about 2-10 min. then drop connectivity. even after all the changes. we did try taking that pc out of the dhcp pool and run as a static ip and still the same results

Once again I ask, how many machines (including printers and routers) are hooked up through that firewall. The sonic wall firewalls are VERY strict on their user licenses. Log into the firewall and check the access logs. It should tell you in there why the connection was dropped.

I've had problems in the past where I went past my user license and it told me right in the logs that I had to many users on the firewall and needed upgrade to more licenses.

i believe it hsould be under 50, however ill have to check (its not my network), but i will take a glance at the logs, however wouldnt the firewall drop all the packets as opposed to just some?

Nope. Not in my experience. It only limited traffic trying to get OUTSIDE of the network. Everything internal worked fine, IE file sharing, printer sharing, network apps, ect.
