NIS service across firewalled subnets
2007-12-25 0:39:00
We hope to subnet a network segement to restrict acccess between production
and development servers.
Segment A will be production servers.
Segment B will be development servers.
Cross-segment traffic will allow ssh/scp for admin workstations only.
We plan to install a NIS master in Segment A.
When we tested out, it seems like NIS clients in segment B is unable to
bound to the NIS master. We noticed NIS clients does a broadcast to it's own
subnet and the firewall is unable to relay the broadcast traffic.
If such firewall blocked segment does not allow NIS traffic, and we have to
setup a NIS slave, does anyone know the port/traffic type require to allow
ypxfr if I were to install a NIS salve in segment B?
Have anyone does similar setups before?
