Hello!
I have a problem with E-mail server on Qmail 1.03 (with
Sendmail I have such problem too).
It work on FreeBSD 3.3 in three subnet"s
and serve three domain"s with one 100 Mb interface card.
This is a picture of subnet"s:
| Internet, PPP to Cisco router
__________
|Firewall| - default router
----------
| Router have only external IP
| First subnet, external IP"s (mask 0xffffffc0)
-----------------------------------------------------------
----------------------
| | Three
IP |
| client PC"s, second subnet, internal IP"s | on
server third subnet |
| (mask 0xfffffff0)
| (mask 0xffffff00) |
__________
___________ __________
| N1 | | Server
| | N2 |
---------- -----------
----------
On this server work Squid proxy and work very well for all
IP"s. But when client connect
to server for E-mail (25 or 110 ports) from internal IP"s,
he must wait
from 2 to 5 minutes to connect. This problem is for local
connect (from server console) too.
Connection from external IP"s is fine (some second"s
maximum).
Why so? I can"t find answer.
Thank you for your help!
