VPN tunnel match list overlaps local LAN

  1. Hi,

    We have four offices which use various subnets under 10.0.0.0/16, these
    are connected with a fully meshed VPN network. Each office also has a
    connection to a larger network using lots of other subnets under
    10.0.0.0/8. Rather than trying to maintain all the individual subnets
    on the last tunnel we wanted to just encapsulate any traffic to
    10.0.0.0/8 on it.

    i.e. access-l mainnet permit ip 10.0.168.0 255.255.252.0 10.0.0.0
    255.0.0.0

    However, this seems to be an issue as the destination overlaps the local
    subnet. Is there a way around this or do we just have to keep updating
    our matching list with more specific subnets?

    Thanks,
    James
