[asterisk-users] Digium TDM400P in Soekris net5501-70?

[Brian McEntire]

Darrick -
You seem adamant, and I will look deeper into the firewall in Astlinux!  :-)

The one thing running monowall in a VM would do for me is (in theory)
make it very simple to move my existing, working m0n0wall
configuration. I've been running it for a while, it serves a bunch of
DHCP clients, does a little NAT, and has 20 or so specific rules for
what can talk to what across the LAN, WAN, and DMZ segments of the
firewall. If Astlinux can do all that, and I can grok it easily, it
might be easier than running m0n0wall inside a VM.

I suppose the other thing running m0n0wall inside a VM might do is a
little extra security. If the firewall is in a VM and the asterisk
part is running on the hardware without access to the LAN ports (which
are all owned by the VM) then it *might* make the asterisk install a
little more secure or less exposed to automated attacks. Not saying
this is a high payoff for me, but another potential pro for a VM
setup.
