SONICWALL TZ350 issue Urgent please
We are running SONICWALL TZ350 from last 3 years and suddenly FW stopped NAT / PAT for newly created Rules.
We were using RDP to one of our LAN system over the wan to manage the FW .
Old rules were working fine after we started checking the Rules we suddenly lost control and now none of the rule is working and even simple RDP default port stopped all HTTPS / HHTP rules also stopped and we have no control to the FW .
We restarted the FW manually powered off but still we are unable to access the FW from WAN and non of the NAT rules are working .
we can ping the FW over WAN and can access from LAN but all NAT rules are not working
Now can you advise is this something observed before?
What to do next ?
Factory reset will work ?
