Hi,

Basically I want to configure a lan to lan with one side behind a NAT. Got no option to remove the nat as this is done by the mobile broadband operator who won't assign public routable IP'S.

Both side have a 2860's with the addition of a 4g router with ip pass through on wan2.

Client vpn works fine on my laptop when connected to the mobile broadband side so I guess this uses some sort of nat traversal?

Is this possible on Draytek's, if so what lan to lan options should I use?

Have the static public IP router accept 'dial in' and have the private dynamic IP router use 'dial out'.

Or use a mobile data SIP which supports fixed IPs:

Hi, thanks I have read other posts regarding this issue and have seen that you recommend this company every time

I know that it's possible to buy public routable IP'S off third party companies and use their apn however data costs allot more than a standard mobile broadband sim.

I would however like to know any recommendations for a setup that is know to work just using 2860 to 2860 via 4g.
