Hmmm. So let me get this straight:

PC-------Sun------Internet
   ^          ^
   ethernet   sppp


1. PC -> Sun : DNS request
2. Sun -> DNS server : NAT'd DNS request   (NAT works here?)
3. DNS Server -> Sun : DNS Response
4. Sun -> DNS Server: ICMP Port unreachable

??

I'd really like to see a packet dump of that. Also, I'm curious what
happens if the DNS server is inside the network, or if you browse by IP
and don't require DNS.

But it translates in 3, rigt? It just gets the ICMP Port Unreachables?

Hmmm - wait, you're ruleset... try just this:


pass in quick on bge0 from any to any flags S keep state keep frags
block in quick on sppp0 from any to any

And let me know how that goes.
