Problem with maiserver moved from lan to dmz



  • Hi all

    I moved a mailserver from the lan to the dmz and I am having some troubles.

    LAN B–------ ipsec -----router-vpn--------LAN A-----------FIREWALL  -----internet
    192.168.2/24                    192.168.1.254    192.168.1/24      192.168.1.251  ---- dmz  (192.168.100/24) - mailserver

    From the lanA subnet (192.168.1/24) is't all ok
    But from the remote lan (192.168.2/24) (connected via an ipsec tunnel between two cisco routers) connections to the mailserver (192.168.100.2) are very slow and clients like imapclients give random errors.
    The ipsec tunnel is 192.168.2/24 > any and any > 192.168.2/24
    In the firewall there is a static route to 192.168.2/24 via 192.168.1.254
    from LANB clients I can do telnet dmz:ports (25-80-143) but I receive answer after some seconds
    I test the system with a pass all in the lan and in the dmz

    what can I check ?
    thanks

  • did you check the box in system –> advanced -->  Static route filtering, you need to do so.
