I was asking myself what could I do to join two networks that are in the same building.
the situation is like that:
networkA (office) - RouterA - FirewallA - SwitchesA - PCs vlan default 1
networkB (guests) - RouterB - FirewallB - SwitchesB - Access_pointsB - Special_PCs and Guest_PCs vlan default 1
suddently There is the necessity to have Special_PCs connect to PCs
I think I could do it with a vpn between the two firewalls, but that might have poor performances. I think I could do it with a cable connected between the two routers and two static routes but I might have not access to the routers. Can I probably do it with a cable connected between the lan ports of the two firewalls and policy rules?
All ap firewall and switches are zyxel.
Wire up a link between routers A and B. Route between the nets. Configure security controls such as segmentation and firewalls per your organization's policy and network design.
Once you have a path between the two, B can reach nodes in A's network. That is the primary purpose of routers, and routing protocols.
