Hi, I would like to hear your opinions about this firewalls' behavior:
In my lan I've 2 gateways, I'll call them: G1 and G2. G1 permits all the traffic of my lan to the other building and G2 provides my lan of internet access. In G1 there is a freebsd box with ipf installed on it. The PCs and 3 servers were configured with default gateway as G2(internet) only one server has the default gateway as G1, this last server has an apache with several applications on it. The other building's users pass through G1->ipf to the apache and get their requests without problems, but recently I've tried to give them pop3/smtp and ssh access to a server whose gateway is G2(internet) and they didn't be able to access them. I realized that if the server is redirected to G1, the users are able to connect themselves to the services. To be sure about it I redirected the server with apache that before was pointing to G1 to G2(internet) and the access was broken. I think the firewall cann't give the answer of the service to the client or the services don't know where to send their answers. This shouldn't be an ipf problem because I've tested it with ipfw and kerio firewall also. I would like to know why happen this?
