#13743 new defect

NAT: port forwarding issues / collision

Reported by: Technologov Owned by:
Component: network/NAT Version: VirtualBox 4.3.18
Keywords: Cc:
Guest type: other Host type: other

Description

Host: Windows 7, Core i7, VBox 4.3.18

Guests: Linux, RHEL6 (CLI-only)

Setup localhost + 2 web servers VMs.

VM1: NAT host@1443 -> guest:443 (default 10.0.2.15 IP)

VM2: NAT host@2443 -> guest:443 (default 10.0.2.15 IP)

I connect by typing in local web browser: https://localhost:1443

When I connect via HTTPS to first VM, it's okay, but when I connect to second VM, the first one disconnects (connection timeout), and then I get access to 2nd VM, and after I try to reconnect to 1st VM, 2nd VM immediately disconnects, so there is some collision between NAT engine on both VMs.

No way to connect to both VMs, from localhost web browser.

Not sure why this happens, as SLIRP NAT module is supposed to be user-space, per-VM process.

I also ensured, that MAC addresses were different in 2 VMs.
