I have 2 routers set up in our office, one an ASA5505 and one is just a smoothwall. The smoothwall has a VPN set up to a data centre rack and users access various servers at our datacentre. I am in the process of setting up the ASA5505 on a new fibre connection and wanted to know if I could route the data centres subnet through the smoothwall's VPN connection. I have a route set up and from the ASA5505 I can ping the servers at the datacentre, however when I am on this connection myself I can't access anything.
Is there something I'm missing here? I tried various NAT rules, however I can't seem to get this to work.
