maybe i didn't explained correctly


1st network:

Firewall (Sonicwall)-->(maybe Sniffer)-->Proxy--> Network

2nd Network

Firewall (Linux firewall) --> Router(with firewall) ---> router (with firewall) ---> Main Network(1st network)

this is why im asking your opinion, if the Hardware firewall is well chosen, and this security implementation, is well defined, or should i change something.

It is not yet confirmed, but the other solution is a direct optical cable, for 1st network to the 2nd network, but duo the highly costs im not sure that will be possible, so im trying to make a implementation plan, just in case.

If they buy the optical, everthing will go trought the Hardware Firewall and proxy.
