Running SuSE 6.3 (2.2.13 kernel.) The machine in question is our gateway machine. Our Internet connection is via eth0; a private intranet is on eth1, with the gateway providing Internet access for the intranet via masquerading. We have two IP addresses on the Internet. One is on eth0, the other on eth0:0. This used to work just fine. Now, however, TCP connections (e.g.: SMTP) to the aliased interface from the Internet fail. Connections from the intranet work fine. Also, eth0:0 can be pinged from the Internet. Now, if I switch the IP addresses around, so that the IP address from the alias interface is now on the "real" interface and vice versa, both IP addresses are available for SMTP connections. They ifconfig eth0:0 down ifconfig eth0 down ifconfig eth0 12.15.47.122 netmask 255.255.255.0 broadcast 12.15.47.255 ifconfig eth0 12.15.47.121 netmask 255.255.255.0 broadcast 12.15.47.255 route add default gw 12.15.47.120 Using 'route add -host ...' doesn't help. Any assistance would be greatly appreciated. -- Ron Oliver (mailto:roliver-suse@quantum-networks.com) -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
