Question

Hi.

I'm trying to establish a VPN between a draytek router and an RTU240 router.

Draytek router has fixed IP, RTU240 has 4g sim.

VPN is ipsec agressive, VPN established and can access web interface of router.

Having trouble accessing devices on remote network (RTU240).

Any guidance would be appreciated.

Answer 1

Are both routers using subnets that are routable to each other? If so, make them different.

Hello,

Try enabling Dead Peer Detection and Keep Alive features on both of the devices.

Dead Peer Detection enabled, don't have the option for keep alive.
