How do I specify the DNS servers for VPN users? It defaults to the DNS servers on WAN1, which are obtained from the ISP using PPPoE, which is no use.

How do I support remote L2TP users on more than one WAN interface concurrently? It looks like the IPSEC general options only allow remote users on one WAN interface.

How do I set the IPSEC MSS for tunnels? I have problems with large packets over IPSEC tunnel with a MTU set higher than 1442 on my WAN interfaces from a 3200. i.e pings are fine, RDS sessions or SMB fail. This doesn't make much logical sense to me.

I can't see options for a lot of this stuff using the web interface. is there a command line reference douument anywhere?

Thanks
