Everything on your IP address set-up looks OK. Now, here's what you need
in the routing tables of the two machines:
Both:
route add -net 127.0.0.0 lo
route add -net 206.196.114.16 netmask 255.255.255.248 eth0
sol:
route add -net default gw 206.196.114.17
knoll:
route add -net default ppp0
or
route add -net default gw 206.196.100.185
After you've done this, things should work fine given one assumption,
that your ISP has his routing tables set-up properly. If they don't, you
can do all the proper network set-up you want and it won't work until
then. As a second note, if these IP numbers were assigned from your ISP,
make sure that the names and numbers in your ISP's DNS tables match what
you have here. Other wise, some servers will deny you access thinking
you are trying to spoof them (many ftp sites are known for this :)
