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?
