Hi folks,
I've been working on getting my WiFi network running with IPsec. I'm
at the point where all traffic on the wifi subnet is encrypted (i.e.
ESP). Then I tried to add AH to the equation. I failed.
This picture describes the network setup:

Here's what I'm trying and failing with. With these rules, I get no
comms between the laptop and the gateway. If I remove the
"ah/tunnel/..." clauses from the sdpadd statements, everything moves
along nicely. What am I missing here?
Any ideas? Thank you.
rules for the laptop (encrypting + authentication)
add 10.0.0.1 10.0.0.10 esp 691 -E rijndael-cbc "1234567890123456";
