charon: 04[NET] error writing to socket: Permission denied

[Simon]

When starting an IPSec VPN I get the following error

charon: 04[NET] error writing to socket: Permission denied

Anyone any ideas what does this mean ?
Keep getting the same error over and over again

I can use the same settings on a Draytek Router to Draytek Router and it works fine

Anyone any idea on this, would be appreciated

After a month or so I have given up with this
Replaced with Draytek 2925, which handles multiple IPSec VPN connections without issue and is very stable
