Hey Hey,

zencoder asked a very inportant question... The hardware that you are using..

the other question is what do you want to answer is what exactly you want the firewall in place for.

If your servers are hardened and properly secured and this is a trusted network, then a firewall is most likely not necessary...

However if they aren't then a firewall is probably a decent way to add a little protection..

You might want to investigate VLAN Maps... they might be able to provide you with the level of firewalling you're looking for.

Anyways if you can answer those questions for us we can be of much greater assistance to you.

Peace,
HT
