Hi,
this is my question: is it possible to use NIS+ if:

- NIS+MasterServer is in one network (named NET_A)
- NIS+ clients are on another network (named NET_B)
- There is a FIREWALL/NAT between NET_A and NET_B
???

NIS+MasterServer has:
- REAL_IP
- NATTED_IP

Clients on NET_B have
- REAL_IP
- NATTED_IP

>From NET_A I send packets to hosts on NET_B using their NATTED_IPs
>From NET_B I send packets to hosts on NET_A using their NATTED_IPs

The commands used to setup NIS+ are:
(on NIS+Master)
nisclient -v -d domain_name -c NIS+Client_NATTED_IP

(on NIS+Client)
nisclient -i -h host_name_NIS+Master -a NATTED_IP_NIS+Master -d
domain_name


With a packet snoop on NIS+Master and on NIS+Client I can see packets
going between two hosts... (because in the first part of communication
they use natted IPs)
....but in the second part of communication I can see that NIS+Client
sends packets to REAL_IP of NIS+Master!!!

The tables on NIS+Master and NIS+Clients are right,
Why Does NIS+Client send packets to NIS+Master REAL_IP???
Where does NIS+Client get NIS+Master REAL_IP ???

Is it possible for NIS+ to work beside FIREWALL/NAT???

Please help me, this issue is critical for me..

Thanks in advance,
