[Serusers] NAT ping and consumer router

[Richard]

Hi Jiri,

As I mentioned before, I was not a big fan of ALG before. I tried ALG on
some devices, too many problems. However I was pleasantly surprised that
linksys has a good implementation, i.e. all the problems I had with other
implementation doesn't have it here.

Just like Nathelper and mediaproxy are temporary fix which introduce extra
media hop, nothing is perfect. Also I experience too many problems of using
cpl with nathelper, trying to figure out how to not mess up with SDP if two
phones behind the same NAT. Being able to access and play with the source
code of linksys is certainly a big plug considering that we don't have
access to source code of any hard phone.

In lieu of a perfect UA, I think this is least evil solution, if you think
this way...

Richard

Hi Richard,

I'm not entirely happy I am so frequent disagreement initiatior in this
thread
but I don't like ALGs too much either. They have a bunch of issues,
primarily they
don't work with security and secondly they have a high potential for 
misimplementing the application logic. This has turned out to be true
in quite many cases in the past. (Nevertheless good to hear there is 
a working linksys product.)
