  • cisco 2651 forward openvpn issue

    Helo,

    I have some issue attempting to forward udp port 1194

    so:

    int fa0/0 _WAN_IP
    ip nat outside

    int fa0/10 _LAN_IP_
    ip nat inside


    ip nat inside source list 100 interface fa 0/0 overload

    access-list 100 permit ip 192.168.100.0 0.0.0.255 any

    ip nat inside source static udp 192.168.100.2 1194 _WAN_IP 1194
    ip nat inside source static tcp 192.168.100.100 25 _WAN_IP 25


    So forwarding of port 25 tcp is working.... but udp 1194 not at all
    Firewall on VPN_server is down and openvpn is up


    i was reading it may be a problem with forwarding udp ports but didn't understand what exactly I have to setup....

    I would create an access-list (you should have one inbound anyway as your outside interface is wide open) to see if you get hits on it


    access-list 100 permit udp any "your public ip here" eq 1194 log
    access-list 100 permit tcp any "your public ip here" eq 3389 log

    (Remember the implicit deny at the end of the ACL)


    See if you get any hits on the acl's. This will tell you if its even reaching the router

      well, it looks like it was necessary only a reboot
