[Serusers] nat problem maybe?

hi again. marian. your suggestion worked great! the lookup warning
has gone away. however my client (i am now using sjphone) is still
unable to register. i was able to get an x-lite cient to register, but
the sjphone (and others) are not able to register. one difference i have
noticed is in the check_via statement. the x-lite client (which is able
to login) lists my public ip twice in the check_via whereas the sjphone
client lists my public ip address first and then my private ip address.
could this have anything to do w/my problem? i am incuding the
ser server's output below. the portion i'm including just keeps
looping over and over again...
thanks again,
daryl
