[asterisk-users] NAT/firewall/Asterisk/Polycom Phones

[Michael Araba]

Are the Asterisk Implementation below recommended?

Scenario One:

Asterisk PBX is installed as gateway with two NICs. The internal NIC
servers a network LAN of only Polycom IP phones while the other NIC is
the public interface(static)

I also have a few Polycom IP phones connecting from homes.

Specs:
Debian Linux, IPtables for Firewall


Scenario Two:
Asterisk PBX is installed as standalone with one NIC (public).

Firewall (IPtables, Debian Linux) with two NICs - The internal NIC
serves a network LAN of only Polycom IP phones while the other NIC is
the public interface (static)

I also have a few Polycom IP phones connecting from homes to the
Asterisk PBX.
