[Serusers] Cisco 7960 don't REGISTER

[Ricardo Carvalho]

Finally it's working, although not as I was expecting, because my cisco 
7960 only registers in the server if I put him outside of my firewall, 
in a public IP. How can this be possible? If I give him an IP in the 
same subnet of the SER server, It doesn't register, if I put him 
outside, it works!! From outside until reach server, in the path there 
is a PIX, routers and switches. While in the same subnet there is only 
one switch!! So strange...
Any clues?

Regards,

Ricardo.
