Gurus,
All our packets after crossing the router lands on our firewall(Natting)
and later goes to corresponding servers according to the firewall rules.
Our primary DNS is configured inside the firewall and these are the
entries in named.hosts
------------------------
; Authoritative data for Berkeley.EDU (ORIGIN assumed Berkeley.EDU)
;
@ IN SOA www.cdfd.org.in. root.www.cdfd.org.in. (
1986020523 ; Serial
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
3600000 ; Expire 1000 hours
86400 ) ; Minimum 24 hours
IN MX 100 www.cdfd.org.in.
IN MX 10 cdfd.org.in.
IN NS www.cdfd.org.in.
IN NS cdfd.org.in.
IN NS sunserver.cdfd.org.in.
IN NS mailgateway.cdfd.org.in.
IN NS firewall.cdfd.org.in.
localhost IN A 127.1
www IN A 210.212.212.3
cdfd.org.in. IN A 210.212.212.3
sunserver.cdfd.org.in. IN A 210.212.212.7
mailgateway.cdfd.org.in. IN A 172.16.0.10
-----------------------------------------
our firewall IP is 210.212.212.2 and hence some of the mails are being
rejected saying
"Permanent error involving remote host.
554 5.7.1 The server sending your mail [210.212.212.2] does not have reverse
DNS entry.connection rejecyted"
How to solve this problem.
Is having the primary DNS outside solve this problem.
Please shower some lights to get this problem cleared so that none of our
mails are rejected.
Thanks
Geetha Thanu
