Linux Issues

[Gorion]

Is there anyone familiar with Centos7, who might solve a problem I have?

Scenario:

A: 1 virtual machine, 3 nics, 1 internal host only communication, 2 externals bonded bridged default route
B: 1 virtual machine, 1 nic, 1 internal host only communication default gateway set to A

Above settings cannot be changed.

Need to give internet access to machine B, via machine A.

Changed all interfaces to trusted via firewalld, also added sources via ip just in case.

Issue: B won't talk to anything outside.  It should, unless I'm missing something.


Update:

When I ping a local IP accessible from B, which is accessible from A, I'm getting icmp replies from A that host is not accessible.  So there is some sort of communication going on, somethings not right though.
