[f-nsp] Problem with NAT Foundry Server Iron XL

Ramon,

   I find that the XLs are not very tolerant of misconfigurations, and when there 
are problems, they just perform inconsistantly like this, rather than logging 
any errors.  So I would look for any duplicate IPs, or duplex mismatches, plus 
any errors on the XL ports, plus any switches/routers that the XL is connected 
to.
