Hello all. I've done a Gateway on FreeBSD4.5 for a
small lan, connecting to Internet with a 56K modem.
On this gateway I've installed also qmail,pop3 and
courier imap for send and receive(fetchmail) mails
from internet.
This the scheme: ed0
Internet----56Kmodem--Fbsdbox---------------LAN
192.168.0.1 192.168.0/24
The problem is that when the modem is disconnected, if
I try for example to "telnet 192.168.0.1 25" from a
machine on the Lan to test q-mail, the q-mail server
takes a very very long time to respond me.
And if the modem is also light-up, he attempt to
connect to internet.
When the modem is connected to internet all works
well.
I use user-ppp in this way:
ppp -auto -nat provider (or with flags in rc.conf)
Looking at the routing tables I see that the default
route is the 10.0.0.2, right because of the ppp.
If I delete the default route ("route delete default")
the q-mail daemon responds ok and also pop and imap,
but the ppp doesn't work because I deleted the default
route.
This is the output of "netstat -rn":
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 10.0.0.2 UGSc 0 0 tun0
10/24 link#1 UC 0 0 dc0
10.0.0.2 10.0.0.1 UH 1 0 tun0
127.0.0.1 127.0.0.1 UH 0 0 lo0
192.168.0 link#3 UC 0 0 ed0
~snip IPV6
And this is the /etc/rc.conf:
gateway_enable="YES"
firewall_enable="YES"
firewall_type="OPEN"
hostname="Walrus.Gsg"
ppp_enable="YES"
ppp_mode="auto"
ppp_nat="YES"
ppp_profile="provider"
inetd_enable="YES"
kern_securelevel_enable="NO"
keymap="it.iso"
linux_enable="YES"
moused_enable="NO"
moused_type="NO"
nfs_reserved_port_only="NO"
sendmail_enable="NO"
sshd_enable="YES"
ifconfig_dc0="inet 10.0.0.1 netmask 255.255.255.0"
ifconfig_ed0="inet 192.168.0.1 netmask 255.255.255.0"
Anybody knows what do I have to do to make the qmail
and other servers have a faster response and Internet
connection working?
Thanks all
