I have successfully built & installed the Shrew Soft VPN client 2.1.7 from
source for a 32-bit Slackware 13.37 system and using a VPN configuration
that is known to work for Windows XP, I'm able to make a connection to the
remote network. The tap0 interface comes up using the correct static IP
address for the remote network and the routing tables appear to be correct
but I cannot connect to or ping anything on the remote network.
Reading the Shrew Soft VPN Linux installation document under the section
headed 'Configure OS' on page 4, it mentions using a text editor to modify
/etc/sysctl.conf. There is no such file in or sysctl utility in Slackware
Linux, where kernel parameters are modified through /proc filesystem with
commands like this example:
echo 1 > /proc/sys/net/ipv4/ip_forward
Can anyone confirm that correct Slackware equivalent settings would look
like this:
cdandy@purdy:~$ cat /proc/sys/net/ipv4/conf/all/rp_filter
0
andy@purdy:~$ cat /proc/sys/net/ipv4/conf/default/rp_filter
0
andy@purdy:~$ cat /proc/sys/net/ipv4/conf/lo/rp_filter
0
andy@purdy:~$ cat /proc/sys/net/ipv4/conf/eth0/rp_filter
0
Finally, the iked log is reporting:
andy@purdy:/var/log$ cat iked.log

What does this mean?
Thanks in advance for any help,
Andy
