Hi all :-)
I have a problem with my current configuration of ipsec. I'm using ipsec with
kernel 2.6 and racoon. I have two computers linked by wireless cards. The first
(192.168.1.1 Zeus) is connected to internet through a DSL modem and the second
(192.168.1.2 Memphis) is accessing internet through the first. I want with
ipsec to encrypt all datas between the two computers.
I can exchange data between the two computers and Memphis can access the
internet but when I tried to download a big file, it didn't work although it
worked fine on Zeus. I've tried to change the MTU to 1300 but it changed
nothing.
I have another problem, when I exchanged data between Memphis and internet, the
ip header is not protected by AH , I can see the destination adress with
tcpdump!
Can somebody help me? Thanks in advance!
Here is my configuration file for Zeus (it's nearly the same for Memphis)
Setkey :
#!/user/sbin/setkey -f

spdflush;
spdadd 192.168.1.2/32 0.0.0.0/0 any -P out ipsec
