Hi, I use Vmware Player 6.0.2 to run linux on my linux machine with no vmware tools. Both linuxes are Slackware 14.1. In my guest system I have a web-server with bridged connection. Both, host and guest, appear with same MAC address and different IPs in my NAT router (self assigned). After some amount of time ( ~16 hours last time) the IP of the guest 'disappears' from the router and my web-server becomes unreachable. Going to the guest and executing wget or opening a page with the browser returns the NAT IP for the guest on the router.
Is it because of some kind of inactivity on my guest slackware?
Or is it specific to vmware bridged connection?

Thanks!

Sounds like an ARP issue. Do you know how long the period of inactivity (for traffic both to and from the server) has to be before this happens?

Next time it happens, try running tcpdump -i eth0 arp on the hypervisor host and see if a connection attempt from the outside generates an ARP request for the internal IP of the web server (it should), and if that request goes unanswered (it shouldn't).

Thanks for response. You are the only person answering to my post, which I have on Vmware forum, serverfault, etc.. So sad..
It happened at random moments, there is no clear pattern. I will try running this script and see if in this way the connection keeps alive permanently.
Executing tcpdump -i eth0 arp throws some error about promiscuous mode.

Even when you run it on the hypervisor?

yes
