| Can't seem to get DCC to talk through my firewall...
| 
| I get the following from running cdcc info
| 
| ################
| # 08/04/04 13:30:22 MDT  GreyList /var/dcc/map
| # Re-resolve names after 15:19:32
| # 1 total, 0 working servers

| indicating that the appropriate port on my firewall is not open.
| 
| I am using Shorewall on a Bering LRP firewall and have added the 
| following rules:

I don't know how to tell shore wall how to do this but you have to
tell it to allow incoming back to ***.***.***.*** which went out on
udp 6277 on an unpriveleged port like 45685. The cisco acl looks like 

 permit udp any eq 6277 host ***.***.***.***  gt 1023
