hello.
i have 3 maschines.
1) ultra1
(hme0 139.23.207.30/hme0:1 139.25.207.27)
2)ultra10
(hme0 139.23.207.28/hme0:1 139.24.207.11)
3)pc(linux)
(eth0 139.24.207.27)
Now i have to build a vpn tunnel/ or another ipsec encryption form, between
the two ultras.
pc< ----(Plain)---->ultra10<---(encrypted)---->Ultra1
But the connection between the pc and ultra10 should be pain-text.
Now i want ping from pc to the second interface of ultra1(hme0:1
139.25.207.27), and the ping packet should be routed through the encrypted vpn-tunnel,
and back.
i use the sunscreen firewall on both ultras.
i used this tutorial
http://docs.sun.com/db/doc/806-6348/6jfa1eop1?a=view
but it don't work, every time when i try to ping from pc to ultra1(hme0:1
139.25.207.27), it is sended as an normal ping.
if i have in the filtering rules only the vpn rule nothing happends, but if
i add a rule which allow all traffic the ping packet will be routed to
ultra1(hme0:1 139.25.207.27)(plain text of course). is this normal ??
where are the logs ??
can i see in any log what is going wrong ??
have anybody helpfull tips?
please help because i have set up my network similar to the
http://docs.sun.com/db/doc/806-6348/6jfa1eop1?a=view
tutorial, the only difference is that i ping not a host but a secondary
interface .
thanks in advance
stefan
