Hi all.
I have a Ubuntu 16.04 server with VMware and a Ubuntu 16.04 guest OS.
The VM host has 1 ethernet interface with a static IP, and also I have added eth0:0 in the /etc/network/interfaces file.
I have a second global IPv4 address that I have assigned to eth0:0
When I ssh into the second IP, it works. I can also traceroute back to it and it looks like it works as it should.
I want all traffic that goes to eth0:0 to be redirected to my virtual machine's network interface so that I can run those two as if they were two physical and independent machines.
I've tried to find some good example online, in forums, etc. But the only similar cases I've run into is where one want to forward traffic from certain ports only. What I want is to just send every little package that comes in to my second IP/eth0:0, straight through --> VM-interface.
I understand that I somehow need to bridge eth0:0 with one of the vmware virtual adapters. So that they would be on the same network so that traffic can be sent between the gateway interface and the guest vm. I also have figured out that I need to do this by using iptables somehow. I have come so far that I have enabled my kernel to allow ipv4 forwarding so that is a go.
ifconfig gives:
Also I'm not quite sure why VMware creates both vmnet1 and 8. Also, I'm not sure if the vmnet1 and 8 even are virtual interfaces at all, since they do not appear in the ubuntu interfaces file - and if it's possible to redirect anything at all to these? Some things aren't 100% clear for me here.
Any advice is appreciated. Just ask if you need more input.
