Ips for NFS and NIS

Some problems this past two weeks arose because the network administrator made me change the server ip for security reasons. It turns out that nfs and nis services went down.

One entire day trying to find the problem and at the end of it y try a simple nmap from a client:

# nmap -sTU host_ip

I don't remember the output but just ssh, http,rpcbind, samba, mysql and postgres ports were open.
NFS just needs port 2049/tcp y udp open.
But NIS needs:

111 tcp/udp
681 udp
698 tcp/udp
701 tcp/udp

Ports that weren't opened.
I don't know which is the problem with the firewall tables but no solution other than come back to the old ip was given to me.
So with clients working I can concentrate in security and the monstrous printers to work using smtp.
