Hello,

As most of us know, GNS3 has problem connecting with outside world on Windows 7 x64. I just tested Windows 8 Consumer Preview(BETA) x64 and installed GNS3 0.8.2 on it. Everything ran smoothly and it could connect to outside world successfully with wired and wireless connections.

Good news to us all.

Have a question though, why is GNS3 much faster on Linux?

Dynamips has been coded for Unix/Linux and must use an additional layer called Cygwin DLL to work on Windows. This slow things down a bit. Also, I guess compilers on Linux are able to better optimize intermediate code and therefore make slightly faster programs. However, I think that for most users, the speed difference is almost not noticeable, especially with fast computers (multi-core etc.) and last Windows versions.

Also, one thing to consider is to have a fast hard drive. Dynamips uses many temporary files to emulate the flash, nvram, create ghost IOS images etc. So the faster Dynamips can write on your hard drive, the faster it is :)

I'm under Win 8 also and having some strange issues. Wireshark on the interface outside of GNS3 shows the packets going out and the responses coming back, but when I sniff on the link inside GNS3, I see the packets leaving, but nothing coming back. I've tried a Loop Back, TAP and direct to the NIC interface. Any suggestions?

OK - setup a simple Microcore vm in gns3. It can do DHCP, but can't ping anything. Same symptoms. Ping goes out - reply comes back as seen by wireshark monitoring the nic, but isn't seen with-in GNS3 capture, only the outgoing. Pinging other hosts inside gns3 works fine..

Just began testing of GNS3 on Windows 8 x86 RTM. First noticeable thing is that WinPcap Library included in AIO package is not compatible with Windows 8. So installer skips it's installation. Continue testing...

Did anyone had a chance to test vlan tagging under windows 8 and if the same problem is present, does win8 strips the vlan tag when you create a trunk from inside gns3 to real switch?

I think it depends of the NIC drivers, not the system.
