Hi,
I understand that there is double NAT happening which is not
advisable.If you are creating a site to site VPN make sure UDP 500 and
IP 50 are allowed on netopia device.If possible turn of NAT on
netopia.So if you turn off NAT on netopia, it will just pass the
traffic to sonicwall where sonicwall will takecare about natting.
Secondly you cant make LAN IP of sonicwall in dynamic IP addressing
scheme.
So make sure on DSL and netopia UDP 500 & IP 50 are allowed.
With regards
