Hi,

Refer sun document 819-0286-10.pdf available for download at
http://192.18.109.11/819-0286-10/819-0286-10.pdf

As per the sub-section "configuring firewall support" within "server
management"

following can be the port allocations for opening the firewall for the
service connections:
1) for the backup server
5+2n
n is number of devices registered on the EBS server
for the current configuration having a single LTO3 tape drive device ,
above count comes to 7
starting from 7937+7=7944

2) for every client i.e. every server 2 port 7937 and 7938
3) there is no separate storage node as the backup server is having
the server software as well as the direct connection to the tape
library.

-------
Refer the page 83 for a possible firewall setting based on above

TCP Packet Considerations
Set firewall rules to allow inbound and outbound TCP packets to and
from the
following service ports:
1)On the Sun StorEdge EBS server - open ports between the Sun StorEdge
EBS clients and the Sun StorEdge EBS
server.============================>7937-7944
2) On the Sun StorEdge EBS storage node - open ports between the Sun
StorEdge EBS clients and the Sun StorEdge EBS storage
node.============================> is the same as storage server in
our setup
3) On port 7937 - open the port between the Sun StorEdge EBS server
and both of the following: - Sun StorEdge EBS clients, Sun StorEdge
EBS storage node on the client side of the
firewall
4) On port 7938 - open the port for inbound and outbound requests.

My query is what about the connection ports? The range of 10001 to
30000 is too large from firewall point of view.
