Change Firewall/Routing conditions on a Unix Firewall

Hello Experts,

I'm working to assist a non-profit with their IT issues. If you could provide any advice or guidance on the issue below I would greatly appreciate it.

There is an internal resource/document database that is (and should be) only accessible internally. The issue is as follows. Only computers/devices in the same subnet (actually, its own network) can access that resource.

Their office recently replace their modem/firewall. Behind that modem/firewall is another Unix firewall (with very basic content filtering, I'm told). My level of unix knowledge is very basic. I had a Unix guru looking at their config with me briefly and he indicated that access to the internal database was restricted on the unix firewall.

How may I pull up the network/firewall config on the firewall and make basic modifications to accommodate this.

Assume I'm a unix noob, because I am! Thank you very much!

Do you know which Unix it is?  AIX, HP-UX, Solaris, one of the other many OS's that are branded Unix.

Since it does not exit to other networks:
Is IP packet TTL bigger than 1
Is default router set on the machine
Is netmask matching what router(firewall?) expects?
