Subject: Re: [Asterisk-Users] How do you handle NAT?
We've been feeling our way along with the NAT stuff (using SIP) as well.
At this point we are fairly small, so the keep-alive packets are not too
bad.
What type of user load are you at and what are the specs on your Asterisk
box?
I'm concerned we may run into this as well.
We do have the luxury that each Sipura device we use is sitting behind its
own
NAT (a customer CPE). So we can do port-forwarding and in combination
with a
STUN server (MyStun), things work quite well. The only issues left to
deal
with are a lingering problem with ip_conntrack entries staying cached
because
of the "keep alive" packets due to qualify=yes after the CPE's IP address
changes.
Curious to hear other's setups as well. I would *love* to start using the
IAXy instead, but it has a couple shortcomings over the Sipura 2002's
we're
using now:
- About $10/more
- Only has one line (apparently two lines is a bit more of a selling
point).
Still trying to figure out a good way to make a case for the IAXy though.

We are interested in how other people are handling NAT problems. We have
several customers all of which have some sort of firewall/NAT device at
their location. For simplicity sake, all customers' internal networks
are 192.168.*.*.
Our asterisk box is on public IP not blocked by any FW/NAT.
I use QUALIFY=yes on all our customers' phones and I feel that sending
out 80-something keep-alive packets is causing our box to crawl and
cause bad calls.
Would SER be better in this case? Should I have phones register with SER
instead of with Asterisk?
Thanks,
Matthew
P.S. Yes, I have read stuff on NAT on the wiki. I'm more interested in
other real world, working, solutions.
