Dashboard 0.8.3_1 IPsec strangeness

jimp

Does it show up this way even after you restart racoon?

The mobile tunnel detection is still pretty new, but this is the only report I have heard lately that it was displaying incorrectly.

I kicked it over, now I'm showing 3/1. That's the two static, the mobile, and the disabled one. So mobile is showing active but down. I guess that's right. (It's configured but not connected) I'll see what happens when the mobile client connects again.

jimp

The mobile tunnel will show inactive until someone connects, and then you'll have one "active" entry per connected client.

dotdash

On my system, overview shows three active tunnels when the mobile client is not configured. Tunnel status shows the mobile client down. I deleted the disabled tunnel that was showing as inactive to simplify things.

dotdash

Got the mobile client connected, now I show five active. That's three for the mobile- one was there and when the client connected via NAT-T it showed one for source IP and one for the destination IP with the NAT-T port. All the mobiles still show down under status.

jimp

There may be some weirdness with parsing your setup… not sure why.

I'd really need to see a sanitized version of the following:

Diagnostics > Command, PHP Execute

print_r($GLOBALS['config']['ipsec']);

Diagnostics > Command, Execute Shell Command:

setkey -D

and

setkey -D -P

dotdash

Ok, here's what I get. Thanks for taking the time to wade through it. I should mention the setup is a CARP cluster, so the tunnels are terminated on the WAN CARP IP.

That worries me. That should be printing a list of all your active SAs.

Do these tunnels show up as 'up' under Status > IPsec?

Seems there may be some other ipsec-tools-related problem on your system.

What version is this running? (Or date/timestamp if it's a snapshot)

jimp

Just had another thought, if this box was upgraded from 1.2-RELEASE to a more modern version it may have two versions of setkey.

Try /usr/local/sbin/setkey -D

dotdash

Ah, that would be it. It was upgraded from 1.2. Good catch:

/usr/local/sbin/setkey -D
