Internet Sharing: Palm Device can't find Internet via USB to Imac G5

Question

None of the internet-using applications on my Palm Tungsten E handheld can find the internet, via a USB connection from the Palm to my Imac G5 and its high speed internet connection.
I have 3rd party software (The Missing Sync 5 from Mark/Space) that is supposed to enable a USB-connected Palm device to share an OS X Mac's internet connection. But I'm not getting beyond the Mac and I think either something on the Imac or perhaps my Linksys router is blocking internet communication to and from the Palm device.
Despite turning off the Mac's firewall and enabling internet sharing in the OS X prefs panes, neither my Palm's web browser nor its mail program can get through to the internet and all I get are communications errors.
I would greatly appreciate suggestions as to what to try next as I have done just about everything I can think of to try to get this Palm to access the internet via the Mac
IMAC G5   Mac OS X (10.4.5)   750 Mb RAM

Hello Adrian - thank you for your suggestions. The USB-connected PALM does NOT show up in The Imac's "Network Ports" - - and the only thing I could add, as a port, that was not already there, was something called "6 to 4" -whatever that is.
The Palm is supposed to be able to get its internet page requests out onto my router and DSL line via the Mac's ethernet port when: A) this Palm is connected to the Mac via USB and B) when the Internet sharing feature is enabled in a software app called - The Missing Sync, which it is, and when C) Internet Sharing is turned on in the Mac 'Sharing' pref. All these conditions are true, but sadly none of the internet apps on the Palm can find the internet .
I suspect a DNS issue - even though my router of course knows the DNS addresses of my ISP.
I should think that the PALM and the host Mac would have the same IP address - namely the one assigned via DHCP by my router when the Mac boots up.
Very frustrating....
I know nothing about Palms but I'll give it a
shot...
You say "Despite turning off the Mac's firewall and
enabling internet sharing in the OS X prefs panes",
are you seeing a USB option in the window? If so
select it.
If not try going to System Preferences>Network>Show:
Network Port Configurations. (This with the Palm
plugged in via USB).
Is it in that window? If it is tick it and go back to
internet sharing and select it in that window. (It
should have now appeared).
If it's not in System Preferences>Network>Show:
Network Port Configurations; select 'New', and click
'Port'. Does it appear in the drop-down list there?
If it does, select it, name it and click OK. (Note:
USB isn't a 'normal' option here but maybe your
Missing Sync will have added it..?)
That will take you back to the main Network Port
Config window where you tick it if it isn't already.
Then go back to Sharing>Internet to see if is
available there. If is is, tick it.
If it isn't, don't know. Sorry.
Have fun!
Adrian
