[Pdns-users] The world can't see me... yet

[NoBloat]

I've set up a master/slave to see how things might go if using pdns for some of our domains. 

On the master/authoritative

allow-axfr-ips=x.x.x.x (the slave server on another network)
disable-axfr=no
master=yes
setuid=pdns
setgid=pdns
launch=gmysql
gmysql-host=localhost
gmysql-user=powerdns
gmysql-password=pass
gmysql-dbname=powerdns
local-address=x.x.x.x (because the server has two NICs/networks

On the slave

allow-axfr-ips=x.x.x.x (the master server on another network)
disable-axfr=no
slave=yes
setuid=pdns
setgid=pdns
launch=gmysql
gmysql-host=localhost
gmysql-user=powerdns
gmysql-password=pass
gmysql-dbname=powerdns

Nothing is getting in or out. The world is not seeing the dns server/s, the dns servers aren't seeing each other. 
What am I missing here?
