Mary.
Settings on my Iphone is like yours.
As described, I have before used my DD-WRT router as VPN gateway, but I did disable that, and instead I forward port 1723 to my SME.
My SME is server only, and not gateway.
I have disabled the VPN server on the router, but when I enable it, I do get external access, but with SME as VPN server. If i disable VPN server on router, I do get internal access only.
On the router VPN passthrough is enabled separately ?
Using SME server as VPN server, should be independent of the router settings, as long as port 1723 and passthrough is set correct ?
Strange.
