A company I work with recently decided to share an office with another company. They wanted to keep the networks separate. So what we did is got a separate IP range from their ISP and had that range routed to our firewall. Everything works fine, except company 1 can’t connect to any of the machines on comapny 2’s network. Here’s a pic to help explain this better:
router (2 sep. valid IP ranges)
| |
co1 firewall CO2 proxy server
| | |
DMZ internal co1 internal co2
Both company 1 (CO1) and company 2 (CO2) can access the internet all everythign just fine, but if someone from CO2 tries connecting to one of the machines i the DMZ of CO1 the connection cannot be made. Also, CO1 cannot ping even the external address of CO2’s proxy server.
I know the problem has to be with the router somehow, but can’t figure it out. Any suggestions would be much appreciated!
