For this, I think you need to enable port forwarding in the Advanced
settings in the Linksys so that all packets on such and such port go to the
internal VPN host. However, note that NAT can cause problems for certain
VPN solutions that use a hash for authentication of the IP header, most
notably IPsec using AH. I have heard that some routers have "PPTP
passthrough," which would make me wonder whether PPTP and L2TP might also
have similar problems in some circumstances. Search google or the
manufacturer of the VPN solution to find out what ports are used... or do a
test and keep an eye on the router log during the test to see what ports.

I might also recommend enabling logging in the Linksys to send all the log
information to 192.168.1.2 which would be a PC with 192.168.1.2 as a static
IP address and a free syslog client such as www.kiwi-enterprises.com to
capture all the logs. This would let you preserve the logs as evidence, and
would also let you use the free www.mynetwatchman.com software to
automatically report hacking attempts to the hacker's ISP. by default, the
logs on the linksys disappear after 20 log entries or about the past
minute's worth of data.
