Hello,

When I use the Strongswan-app on my Android device and establish a
tunnel to my vpn server, the device sends more packets than are received
and the tunnel is very slow. Is this usual? Is there a fix for this and
could my firewall be the cause of the problems? The firewall doesn't say
anything, but logs and drops packets, which don't fit a rule. The policy
of it is "DROP".

Strongswan version is 5.0.4 and the app on the device is up to date.
Please help me.

Regards,
Noel
