Hello,

tl,dr; how to force Bridge over NAT as default VM network adapter ?

I had a lot of failure with CMS app, until I figure out the issue : network. The machine where I want to run CMS doesnt have a gateway (ip of the router), everything goes through a squid proxy with only whitelisted domains allowed (a kind of paranoid security config).

Altough CMS app detects the squid proxy, it uses alot of direct connect attempts while initializing afaik... thus failing in my current computer.

I managed to change the network adapter config from NAT to Bridge (while Boinc was turned off) and then everything seemed fine for the CMS VM (much faster start, computing working, etc). But i need to overwatch Boinc activity, because any new CMS task will revert to a NAT ethernet adapter.

Is there an xml somewhere that could forcefully mount the VM network adapter in Bridge mode ?

This can't be configured.
The network settings are set to NAT by vboxwrapper and the options you request are hardwired.

You should ask your network/squid admin for permission to run BOINC apps and to change the squid/firewall configuration accordingly.
