guest in Bidged mode can be PING'd but not TELNET'd ????

Post by leo.lagos »

Hi All,
I have a Win Host using latest VBox (6.10). I installed a CentOS guest, which is working fine. On that CentOS I installed Apache server so I have an httpd on port TCP/80. I've disabled SELinux and stopped firewalld.
I changed the default NAT in VBox to Bridged Adapter, since I want to see the apache web pages from my Win Host using any browser.
Result:
1. I can ping the guest from the host OK.
2. I cannot connect to the httpd using any browser
2.1 I also have cygwin+telnet. From cygwin I can ping OK, but telnet to port tcp/80 fails.
2.2 I also installed zenmap (nmap Win), and it cannot see the host neither with ICMP nor TCP (full scan says host down!?)
3. I have 2 computers (personal and work). Tried in both, and same result (both on the same LAN; personal doesn't have any firewall btw).
So, what could be wrong?
I'm using a LAN adapter on the host, so I'm using the same LAN adapter in the Bridged Adapter settings.
Any help would be greatly appreciated!
TIA!

Right-click the guest in the main Virtualbox window's guest list, choose Show in Explorer. Zip the guest's .vbox file, and post the zip file, using the forum's Upload Attachment tab.

Also please post the text outputs of 'ipconfig /all' on the host and 'ifconfig' on the guest.

Generally if you can ping even just one way on a network, that confirms the network is working and other OS filters are interfering with particular communications.

I just tried SSH to the guest, and that also works... so most probably is some Apache configuration...

Thanks a lot!
