LAN routing problems

    Ok... I have a very silly network setup.. but I'd like to keep it this way if I manage to get around its problems.

    I have two AG241V2 modem routers handling two ISP connections. one for lan network-client web and mail the other for web services and sharing (ftp and mail serving for example).

    Both AG241V2s (fw 2.01.00) live on a 10.0.1.0/24 subnet (10.0.1.1-browsing and 10.0.1.2 for services).

    The WiFi connections and IP address assignment are handled by a WRV200 (fw 1.0.20) operating on a 10.0.0.0/24 address space with "externall" address 10.0.1.1 connecting to 10.0.1.1 .

    Reasons for this setup are for example: two layers of firewall protection, possibility of seamlessly switching to other ISP (10.0.0.2) in case of emergency, resource sharing with another lan (10.0.2.0/24).

    One of the main problems I'm having is that some services like AIM messaging now fail...

    What should I play with? I tried setting the WRV200's
    Setup > Advanced Routing > Operation Mode to Router instead of gateway
    but this made things worse so I dcided not to mess things further and ask for help...

    Here are the tables for esier understanding

    WRV200:
    Code:
    [        Destination  ][         LAN IP  ][  Subnet Mask  ][  Gateway Interface  ]
    [  Default Route (*)  ][  255.255.255.0  ][      0.0.0.0  ][  LAN&Wireless       ]
    [           10.0.1.0  ][  255.255.255.0  ][      0.0.0.0  ][  WAN                ]
    [          239.0.0.0  ][      255.0.0.0  ][      0.0.0.0  ][  LAN&Wireless       ]
    [  Default Route (*)  ][        0.0.0.0  ][     10.0.1.1  ][  WAN                ]
    [          127.0.0.1  ][        0.0.0.0  ][    127.0.0.1  ][  LOOPBACK           ]
    AG241V2:
    Code:
    [  Destination  ][           LAN IP  ][  Subnet Mask  ][ Hop ][  Gateway Interface  ]
    [  222.22.2.28  ][  255.255.255.252  ][      0.0.0.0  ][  1  ][  WAN (Internet)     ]
    [     10.0.1.0  ][    255.255.255.0  ][      0.0.0.0  ][  1  ][  LAN                ]
    [      0.0.0.0  ][          0.0.0.0  ][  222.22.2.29  ][  1  ][  WAN (Internet)     ]

    Thanks in advance for any feedback!
