OpenVPN access to remote IPSec network



  • Hello, community!

    IPSec tunnel is configured and accessible from local network.
    OVPN network a.a.a.0 is already added to crypromap on both sides.

    Is it possible to reach remote IPSec network from OpenVPN clients?
    if I add
    push "route b.b.b.0 255.255.255.0" to OVPN server config and add iroute b.b.b.0 255.255.255.0 to client config. Will it work?



  • I'm trying to figure out the same thing and not having much luck.  I recall there being something related to passing traffic through due to some limitation of an IPsec and OpenVPN Certificate tunnel.  Anyone recall anything like this?

  • I see ALOT of people trying to connect site A to site B

    Then site C to site B.

    Then get site A to talk to site C via site B.

    My advice?  Dump that.  Don't even try.

    Try using a full mesh VPN like TINC at all 3 points and then everything with happily talk to everything else.

    IPSec also works. In small networks it isn't complicated to setup. With 3 sites, 3 tunnels give full mesh connectivity and no routing issues.
