sonicwall vpn client issue with cambium nat

Products PMP
1

Hi, one of our customer need to uso a vpn with a sonicwall client; it seems that the cambium nat does not permit to the vpn to login into server. It happen with cisco vpn client too; I tryed to enable the dmz but this not made changes. Maybe the only way to solve it is to disable the nat and use pmp450 as bridge.

Is there a way to solve it without disabling the nat ?

thanks, Mauro.

nobody has the same issue? i think the NAT of the cambium sm sometime is a a problem; the vpn doesn't work....and SIP connection from outside doesn't walk thorugh the nat; the only way to fix it is set the SM in Bridged Mode, and intall  a 3rd party router....; but i would like to find the  solution without installing more hardware....

Did this ever get resolved?

We experience this and have always bridged units but now we have a client for whom we cannot bridge...

Running 15.1.3

We made some fixes for this in previous releases.

I am now using 16.0.1

I have a client who again requires VPN using IPSEC (for an Aruba box) and for whom previous workarounds do not work.

NAT is working for all traffic on a laptop but VPN for Aruba is not coming up. There is no local management console on the Aruba so I have no diagnostics.

Client cannot set up VPN on laptop to test either.

Hi,

Hi Chitrang,

I do not currently have an appropriately configured SM to grab engineering.cgi from.

We will be testing deployment again soon with customer and I will send on then.

Bump.

Further feedback from customer is their provider advises Aruba box requires NAT-T (udp port 4500).
