[SOLVED] RHEL7 guest on windows host : no network connection

Post by Saiimone »

Hello community,

My latop is running Windows 7 using wireless adapter. I installed VirtualBox 5.2.8 and I'm attempting to install a RHEL 7.4 as a guest operating system (network translation is NAT).

Installation is fine but networking is not working, direct result is my guest system is completely isolated and cannot connect with the outbound.

I looked on the web and try several configurations without success.

My previous experience with VirtualBox is it's easy to install a guest system but I don't understand why I'm struggling now.

I'll appreciate any help to resolve this issue. I believe if I don't fix this, I'll be having problem testing vagrant also to deploy several VMs

From my host system, the output of 'ipconfig /all' returns the following

Code: Select all

C:\Users\MyUserName>ipconfig /all

There is something wrong in your copy/paste process. I edited your message to include the output in the "code" tag, but then I noticed something weird:
  • All colons ":" are replaced with "is " ("i", "s", <space>).
  • Periods separating addresses do not show up. Example:

inet6 fe80is is 7702is 9b96is eff6is f78 prefixlen 64 scopeid 0x20<link>
Could you edit your post and fix the issue? I don't want to do too much editing, I might correct something that I'm not supposed to.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

Could you show the output from

route -n

on the guest?

Also see whether you can ping 10.0.2.2 from the guest.

Sylvia.

Hi Socratis,

Apologies for the late answer.

I corrected the

Code: Select all

 part that was containing 'is part'.

Feel free to contact me if anything is wrong or missing.

Thanks

Hi Sylvia,

Sorry for answering lately but I'll try to follow closely the forum now.

I added in my original post the output or 'route -n'

Thanks

Hello all,

Somehow the problem is fixed now !!!

The IT teams install a program named AutoProxy to allow us to work in our different offices or from home and it seems it corrects my issue.

I might be wrong but it's the only change on my laptop I'm aware of.

Thanks Sylvia and Socratis for your messages

Best

S,
