Netscreen XP FW with Linksys BEFW11S4 (trouble)

    Hello,

    I need a little guidance on this; your help is appreciated!

    I’m trying to connect a Netscreen 5XP firewall (2 Interfaces) with a Linksys Wireless Access Point Router (BEFW11v4) to my broadband DSL connection.

    Starting from the Internet:
    First comes the DSL Modem, then the Netscreen FW, next the Linksys Router.

    I set the Trusted Interface of the Netscreen Firewall with 192.168.1.1/26

    I connect the DSL modem to the Untrusted interface on the FW. I setup the interface to use PPOE (on Untrust) and to use NAT on the Trusted Interface. I plug my laptop into the Trust interface w/ appropriate network configuration, test the Internet and it works.

    Now, I remove my laptop from the FW and connect the linksys to Trusted on the FW and the WAN Port (on Linksys). I configure the router for “router mode†instead of gateway. I configure the WAN Connection Type to use static IP using 192.168.1.2, subnet mask 255.255.255.192 and use 192.168.1.1 (FW) as the default gateway. For LAN’s IP on the Linksys I use 10.0.0.1/255.255.255.0 and enable DHCP which works. I plug my laptop into the Linksys and get an IP address. I can’t get to the Internet. I can ping 10.0.0.1 and 192.168.1.2. However, I can’t ping the 192.168.1.2 (FW trust Interface).

    I’ve tried adding static routes, but haven’t had any luck. Here is the routing table autoconfiged by Linksys

    Destination LAN IP Subnet Mask Default Gateway Hop Count Interface
    0.0.0.0 0.0.0.0 192.168.1.1 1 WAN
    10.0.0.0 255.255.255.0 0.0.0.0 1 LAN
    192.168.1.0 255.255.255.192 0.0.0.0 1 WAN

    Thanks for your help.
