If your exports are by hostname instead of address and you do not have a 
local dns server for their zone, then the problem is that nfs is trying 
to look up the hostnames and times out contacting the nameservers listed 
in /etc/resolv.conf before giving up and not providing those exports.

The simple thing to try if I am right about the exports is to use ip 
address or subnet based exports.

Another possible problem could be domain name based entries in 
/etc/hosts.allow and /etc/hosts.deny if you configured tcpwrappers 
restrictions for nfs.  If that is the case these too could be changed to 
ip subnet based instead.

The longer solution, but one you might want to work on, is to configure 
a caching dns server on your gateway, and then add forward and inverse 
zones to it served locally which define the local address/hostname 
mappings.  Then point your nfs server box at that dns server instead of 
the ISP's servers.
