natd used to translate any dns connections to local dns server 91.222.48.5
natd started via cmd "natd -t 91.222.48.5 -p 8485 -a 91.222.48.3"
ipfw rules used to forward dns traffic
divert 8485 udp from 91.222.48.0/22 to any 53 in via em0
divert 8485 udp from 91.222.48.5 53 to 91.222.48.0/22 out via em0
after start at first time nat work normally
In {default}[UDP] [UDP] 91.222.51.124:5678 -> 94.247.43.254:53 aliased to
[UDP] 91.222.51.124:5678 -> 91.222.48.5:53
Out {default}[UDP] [UDP] 91.222.48.5:53 -> 91.222.51.124:5678 aliased to
[UDP] 94.247.43.254:53 -> 91.222.51.124:5678
In {default}[UDP] [UDP] 91.222.51.124:5678 -> 185.208.208.141:53 aliased to
[UDP] 91.222.51.124:5678 -> 91.222.48.5:53
Out {default}[UDP] [UDP] 91.222.48.5:53 -> 91.222.51.124:5678 aliased to
[UDP] 185.208.208.141:53 -> 91.222.51.124:5678
but after some time returned dealiased ip sets to one value and not recognize
from aliased address:
In {default}[UDP] [UDP] 91.222.51.124:5678 -> 1.1.1.1:53 aliased to
[UDP] 91.222.51.124:5678 -> 91.222.48.5:53
Out {default}[UDP] [UDP] 91.222.48.5:53 -> 91.222.51.124:5678 aliased to
