DNS dual WAN & DUAL LAN, dns failure



  • Hi all,

    I hope you can help.

    the setup :
    Device:
    five port soukris

    WAN -> DSL ( static isp ip )
    LAN -> 172.16.8.233/24
    WAN2 -> ISDN (static ip) 192.168.253/24
    LAN2 -> 172.16.42.1/24

    rules WAN & WAN2:
    allow all from LAN net (gateway = WAN & WAN2 ip respectively)
    allow all from LAN2 net (gateway = WAN & WAN2 ip respectively)

    rules LAN
    allow all from LAN net (gateway = gateway_pool)
    allow from LAN2 net to LAN interface ( gateway = gateway_pool)

    rules LAN2
    allow all from LAN2 net ( gateway = gateway_pool)

    gateway_pool:
    WAN gateway/ monitor=nexthop ip
    WAN2 gateway/monitor=nexthop ip

    NAT
    outbound NAT
    WAN 172.16.8.0/24
    WAN 172.16.42.0/24
    WAN2 172.16.8.0/24
    WAN2 172.16.42.0/24
    The problem is the following:

    from the default lan port everything works fine, irrespective of whether I use DNS forwarding with or without dhcp, set the dns manually on the client etc. it does not matter.

    From the LAN2 port ip works fine, but DNS fails completely, whether I use DNS forwarding with or without dhcp, or etc etc.

    Initially the two LAN's shared the same physical networks ( i.e. interconnected switches), just to be on the safe side I seperated them completely, but the same problem occured.

    What am I missing ?

    Thanks,

  • rules LAN2
    allow all from LAN2 net ( gateway = gateway_pool)
    allow from LAN2 net to LAN interface ( gateway = gateway_pool) port = dns
