I've reset that MTU to 1472 and restarted everything and that has had no
effect. The W2K install is actually out of the box as is the working XP
install so I'm not expecting anything untoward there.. ipsec verify shows:
Checking your system to see if IPsec got installed and started correctly:
Version check and ipsec on-path [OK]
Linux Openswan U2.4.6rc2/K2.6.17-1.2145_FC5 (netkey)
Checking for IPsec support in kernel [OK]
NETKEY detected, testing for disabled ICMP send_redirects [OK]
NETKEY detected, testing for disabled ICMP accept_redirects [OK]
Checking for RSA private key (/etc/ipsec.secrets) [DISABLED]
ipsec showhostkey: no default key in "/etc/ipsec.secrets"
Checking that pluto is running [OK]
Two or more interfaces found, checking IP forwarding [OK]
Checking NAT and MASQUERADEing [N/A]
Checking for 'ip' command [OK]
Checking for 'iptables' command [OK]
Opportunistic Encryption Support [DISABLED]
Is it possible there is something wrong with my certificates? I'm still
a bit unclear about how to set all that up even having spent hours
surfing for documentation on how to do it properly. It seems odd though
that the very same certificate works on the XP box and not the 2K box...
