  1. 802.11g setup - MS Windows network neighborhood problems - double NAT issue?

    I am attempting to add 802.11b/g to our office network. The current
    configuration is as follows:

    SBC DSL phone line wall jack, one line out;
    into an Efficient Networks SpeedStream 5861 DSL Modem/Router, one line
    out;
    into Checkpoint NG firewall, one line out;
    into Hawking 16-port switch PN636ES, 16 lines out;
    one of which into Netgear WGR614 v2 wireless router.

    Now, the current setup has the Netgear router set up to do DHCP,
    therefore the wireless clients will all be double NAT. I am able to
    wirelessly access the internet with this configuration, but I cannot
    see any other computers on the local network (network neighborhood). I
    *think* I was able to see them previously with this configuration, but
    I am not sure because of the many configurations that I have gone
    through over the past few days.

    Now, assuming I want to keep the current set up, is there some
    setting(s) or tweak(s) that I'm just not seeing that will convince the
    wireless client to see the other computers (only one wireless client
    connected to Netgear router, all other clients are wired to the
    Hawking switch)?

    I've tried disabling DHCP in the Netgear, but then I run into other
    problems (as I recall, it makes the internet disappear for the
    wireless client). Putting the wireless router before the Checkpoint
    (plugged directly into the DSL modem) is not an option for security
    reasons. Putting the Netgear after Checkpoint but before the Hawking
    switch is (I believe) not an option because of NAT issues.

    If anyone can point me to some resources to hack through this, I would
    greatly appreciate it. Also, people who are willing to show me where
    I've gone horribly awry and how easy it is to set up are free to show
    me the error of my ways. Thanks in advance.

    Note:
    All the computers are Windows machines running XP or 2k except for the
    Checkpoint server (UNIX).

    Follow-up to the above:

    I'm thinking that perhaps the problem is that the Netgear router
    cannot bridge NETBEUI. I would configure it to bridge NETBEUI if I
    knew how, because I can't imagine that it would be a security risk
    because of the Checkpoint firewall.

    The alternative seems to be to create direct shortcuts to various
    computers base on IP addresses... but this is both time consuming and
    may also only work in one direction. I know that I can connect from
    the wireless client to the switch clients, but I'm not certain that
    I'd be able to go the other way.

    As always, advice is appreciated.
