UCP Install restricts access to Subnet


(Kctesting) #1

Hi,

I have RHEL7.5 with Docker EE 2.0

Docker Enterprise Engine: 17.06.2-ee-16
UCP: 3.0.5

All fine but as soon as I install UCP:
( docker container run --rm -it --name ucp -v /var/run/docker.sock:/var/run/docker.sock docker/ucp:3.0.5 install --host-address x.x.x.x --interactive )

I cannot ping\access that server from any other subnet apart from the one where the server is when installing UCP; without UCP I can ping/ssh/access that server from any subnet as designed within our Network.

I know that iptables are modified but all are disabled…so a bit puzzled?

SELinux: disabled
Firewalld: Inactive
iptables service not loaded

Any advice? what am I doing wrong?

I believe this is the issue which I’m experiencing ( routing through wrong interface ) rather than Firewall:
