Hello,

when I have this in /etc/sysconfig/network-scripts/ifcfg-eth0

TYPE=Ethernet NAME=eth0 NM_CONTROLLED=no ONBOOT=yes DEVICE=eth0 USERCTL=no ... IPV6INIT=yes IPV6ADDR=2001:DB8:DEAD:BEEF::10 IPV6ADDR_SECONDARIES="2001:DB8:DEAD:BEEF::20 2001:DB8:DEAD:BEEF::30 2001:DB8:DEAD:BEEF::40 2001:DB8:DEAD:BEEF::50" IPV6_AUTOCONF=no IPV6_DEFAULTGW=2001:DB8:DEAD:BEEF::1 IPV6_DEFAULTDEV=eth0

I have a virtual server, and there are the alias addresses splitted, e.g. IPv6 2001:DB8:DEAD:BEEF::40 is used by BIND (named, authoritativ DNS server) IPv6 2001:DB8:DEAD:BEEF::30 is used by MTA (postfix, DNS has this for MX of this domain) IPv6 2001:DB8:DEAD:BEEF::20 and 2001:DB8:DEAD:BEEF::10 are used by Apache (httpd) ...

and this is also splitted in the firewallconfig ip6tables

-A INPUT -d 2001:DB8:DEAD:BEEF::30 -m tcp -p tcp --dport 25 -m state --state NEW -j ACCEPT -A INPUT -m tcp -p tcp --dport 25 -j DROP

-A INPUT -d 2001:DB8:DEAD:BEEF::40 -m tcp -p tcp --dport 53 -m state --state NEW -j ACCEPT -A INPUT -d 2001:DB8:DEAD:BEEF::40 -m udp -p udp --dport 53 -j ACCEPT -A INPUT -m tcp -p tcp --dport 53 -j DROP -A INPUT -m udp -p udp --dport 53 -j DROP

where can I define which IPv6 address is used as source IP, when doing e.g. wget ... ssh ... ... | mail test@example.com ...

Thanks, Walter
