Docker with Juniper VPN

Dear Docker community,

I hope I post this in the right forum. Anyway, my problem is that straightforward:
I need to run docker with Juniper VPN to connect to resources at my work.

Once I have started the vpn client, the docker container does not see the network anymore.
I have tried to restart the docker engine after I established the VPN connection, but still no dice. Still network is unreachable…

I looked briefly at the network options: --default-gateway, -b BRIDGE, etc However, I am not network savvy enought to troubleshoot this.

On the host, when I run route I see this
[hans@eng-hkramer ~]$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface UG 1 0 0 tun0 UG 1024 0 0 wlp3s0 UG 1 0 0 tun0 U 10 0 0 wlp3s0 UH 1 0 0 wlp3s0 UGH 1 0 0 wlp3s0 UG 1 0 0 tun0 U 10 0 0 docker0

I am rather puzzled about the two default gateways… so I figured I need to specify --default-gateway=
… that didn’t fly.

So please, help is appreciated!
