If you have enabled the SSLVPN you will probably have changed the management port to something else… generally 8443 but you can check this in the System – Administration menu. you should see the port setting in the HTTPS administration port setting.
Now, to diagnose, I had a constant running ping… When I either disabled ping under interfaces, or, changed the source away from any under firewall, the ping stopped…. so I am sure that this is where I need to make the change… However, I just can’t seem to connect via SSH/HTTP/HTTPS…
I just had an idea that maybe this /31 subnet goes much deeper in the firewall and after changing the subnet from /31 to /30, I confirmed everything worked fine – so confirmed that the issue is due to SonicWall not supporting /31 subnets – even if it successfully applies via DHCP.

I am trying to make a few changes on a firewall by connecting remotely to a desktop at work. I need to do a change that I think may reset and change the LAN interface…. I am worried about being kicked out and having to travel to work to reset it.
Also check the logs of the firewall after trying to login. If its being denied it should go tell you and hopefully give a useful reason why. if you still have problems please port the logs and I will have a look.
