    Multiple Subnets on IPSec VPN tunnel Needed

    The Feature that is really missing is the ability to define multiple subnets on the "Remote Group Setup" section of a "Gateway to Gateway" IPSec VPN Tunnel.

    I have used much less advanced routers with this feature and I would reccomend my company replace all of those old unmanagalbe routers with RV082's except if they had this feature.

    As far as I know:: IPSEC calls for multiple tunnels if a single inclusive subnet can't be setup. The spec allows for this and the overhead after the 1st tunnel is minimal.
    Some proprietary versions do it on one tunnel but it ties you to that vendor.

    The problem isn't multiple subnets it is multiple tunnels that the RV can't do if there is any 'apparent' conflict. It isn't a conflict by the spec but the RV thinks it is. A spec legal tunnel pair like this can't be saved on the RV:

    You could then set your subnet to something that includes both nets like 0/16 but then the RV complains that it overlaps another tunnel if you have one to a 2nd location. I haven't tried a star layout but that too might be tricky to fool the RV into running.
