SonicWall Firewall

I setup a NAT on my sonicwall from private to public IP addresses, under Routing I added a line that allow ANY to access the internal device (which is a MPLS router). Under services I ensure I allowed SSH, under Firewall, Access Rules I added a rule that allow WAN to access the device, however when trying to access the device remotely I get connection time out and in the log I see a link that says Network Access, TCP dropped.
Did I missed anything? any help will be much appreciated.
Thank you

at first, accessing a device behind NAT from external to internal is not addressed by routing. it is port forwarding.

secondly, for SonicWALL NAT, commonly two steps should be done.

1. enable WAN -> LAN access on specific ports by Firewall rules.
2. enable NAT mapping from WAN IP to internal IP on the same ports by NAT policies.

lastly, for troubleshooting, you may use its diagnosis tools to trace the packets and find out where stops the traffic.

Thank you for your respond, I do have access list setup from WAN to LAN I open it for ANY just to test, also the NAT looks good in terms of setup, the trace route does fail on the spot, where else can I check if something is blocking this access?

a trick is to monitor if there is any traffic collected on the given NAT policy or firewall rule. just move your mouse over the Traffic Statistics icon, no need to click, you may see the byes and packets that have been received and transferred.

you may simply clear the statistics then run your test and check if there are new numbers there. if yes, it means the rule has been applied on the event. if not, the rule is not used therefore somewhere in your rules is wrong.

It is all on zero, I called Sonic wall support and they confirm that the configurations are correct, what else can be the issue?

Hi rfinaly,

I'm surprised SonicWALL tech support didn't pinpoint the issue! What did they say the cause was?
