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!
