Hey Rich, Thanks so much for the help. I built a new disk, and everything seems to be working now! Thanks again for helping me out. I really appreciate it.

Typically only one pc at a time on your internal net will be able to connect using ipsec. Otherwise it loses track of what goes where. Here is how I added the rules. In /etc/ipfilter.conf, I added the line below. I have included some previous lines so you can get your bearings. Note, I used 208.140.33.0/24 to limit the number of "good" addresses. My IPSec client uses a host inside that range. You could very well use 0.0.0.0 and it would work just fine. # Clear any garbage rules out of the filters ipfilter_flush # Set up Fair Queueing classifier lists ipfilter_fairq # Rule added to allow Protocol 50 for IPSEC forwarding $IPCH -I input -j ACCEPT -p 50 -s 208.140.33.0/24 -i eth0 Then in /etc/network.conf I added the same network to the end of UDP services open to the world. Again substitute 0/0. Note the underscore 500. That is what tells it port 500. UDP Services open to outside world # - srcip/mask_dstport # NOTE: bootpc port is used for dhcp client EXTERN_UDP_PORTS="0/0_domain 0/0_ntp 0/0_bootpc 208.140.33.0/24_500" Good luck.
