IOS Cisco IPSec and Client NAT

Hi,

I've setup the Cisco IPSEC Client on IOS devices and this is working correctly as long as the Astaro does not detect NAT on the client.

I've been reading through the forums and found a host of issues, but can't spot one providing a workaround or fix.

Can anybody point me in the right direction?

Thanks,

Iain.

Hi Scott,

It's working for me, but only when Astaro doesn't detect NAT on the client.

I'm getting the same issues on both IOS 6 and IOS 5.1.1

I'm happy to concentrate on IOS 5.1.1, I assume this should work?

If I use an iPad 1, using a mobile carrier with no NAT then it connects fine.

As soon as I switch to Wifi or change to a carrier that Astaro detects NAT then it fails.

Is it possible to force NAT-T off for Astaro IPSEC? I've seen posts for Cisco hardware doing this as a workaround?
