Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Aim: To be able to access RStudio Server page from other internal PCs (all windows)

I barely know linux and everything I've done so far has been due to walkthroughs and the helpful responses to questions on this site. If anyone is able to point me in the right direction of what to do next I'd be a happy chappy!

Windows 7 host
VirtualBox 4.2.10
Ubuntu 12.04 LTS Desktop
CNTLM installed with pointer to proxy with hashed credentials
Two network connections: 1) NAT 2) Bridged to it's own NIC
NIC MAC address and Bridged adapter MAC address matched
IPv4 properties coded with static IP details
Static IP's details registered on dns server

Ping enabled in UFW and service restarted
Port 8787 enabled on UFW (sudo ufw allow 8787) The host can ping IP
The guest can ping host
The guest can ping my PC
my PC cannot ping guest

Reply from myPCIP: destination host unreachable.

Turned out most of my problems were arising from an incorrectly configured floor port. Once this was correctly configured I was able to get the DHCP and gateway issues solved.
