I’ve replaced it by a bind recursor. Excerpt from named.conf:


options {
directory "/etc/namedb";
pid-file "/var/run/named/pid";
dump-file "/var/dump/named_dump.db";
statistics-file "/var/stats/named.stats";

zone "." {
type hint;
file "named.root";
};


Provides central authentication services, file and printer sharing for Windows and Unix clients. Local logon credentials are taken from LDAP, too.

Tested on fedora core 4 and slackware 10.2.

I think this is a bad move from Linksys/Cisco as most of the pieces sold were used with custom firware.
Need to use other wireless routers, such as Asus, Netgear.

Some alternatives in my wiki.

Tried manual and IKE, SAs up but no traffic through the gif device. Perhaps D-Link could add more troubleshooting functions into their firmware (e.g. show routing table, SAs, disable NAT, routes through PPTP or L2TP tunnels).
