Sonicwall TZ210 locking down SSLVPN

We have set up a couple of users to connect to the TZ210 and download the NetExtender client. They can connect with the credentials we have given them and use the resources on the lan that we have allocated them.

We would like to lock this down by only allowing incoming connections to come from one or two specific ip addresses in order to increase security, but are unsure how to do this.

Does anyone know how this is achieved on the TZ210 please?

I think it would be possible to create a Firewall rule to allow only the external IP addresses you want and then do a deny any for the second rule. This would be applied to the WAN>SSL VPN zone.

Thanks for pointing me in the right direction. Everything locked down to user level and working well :-)
Awesome!  I'm glad I could help and thanks for the points.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
