Now that my issue with the initial connection is solved. I have another issue regarding nrtap becoming the primary interface on an arch linux system when nrclient.service is running.

First off, I am using Arch linux, Gnome and NetworkManager. When I have the nrclient.service enabled the nrtap interface IP becomes the primary IP on my client-side lan. For instance when I try to ping http://www.google.com or a local machine on my lan it tries to ping from the nrtap interface IP (10.0.0.x).

Any thoughts would be appreciated.

Thanks!

PS. I will test in an ubuntu VM and see if I get the same results

EDIT: Would be happy to write up some tutorials if I can get this thing going.

Same issue on ubuntu 13.10 x64 with x64 version of nrclient. I am able to successfully connect to a neorouter domain however that dumps all lan connectivity. Pinging internal IP's are defaulted from nrtap's IP as well. I can only ping other nrclient's. The only way to get DNS is by adding it to resolv.conf manually but that only works for extranet name resolution not intranet.

Hmm... I just found out that I can ping anything within my current subnet/vlan. For instance I'm on a 255.255.248.0 subnet. I am able to ping anything within that subnet range. However, if I try to ping something in another vlan the nrtap IP (10.0.0.x) is trying to ping. I've tried forcing my eth0 interface to ping outside of my vlan and I do not get a reply.

eg:
ping -I eth0 x.x.x.x

Would there possibly be any routing stuff I would need to adjust for the nrtap interface?

Sorry for blowing up this thread... Just trying to post all the relevant information I have.

Ok now on a windows 7 VM. Everything seems fine. I am able to ping out of my vlan out of the box. At first when I ping an IP in a different subnet the "NeoRouter Connection", for the first ping fails but windows auto-switches and tries my primay "Local Area Connection" which then pings fine.

So no problems with windows, all is good going across vlans. The only configuration I did have to do is add my local DNS IPs to the "NeoRouter Connection" for IPv4.

Anybody have any suggestions why I'm not able to contact any clients outside of my vlan? Not the neorouter vlan. My actual network is split into various vlans.

Hi jz-train,

It looks like routing problem. Please check your route table. NR client uses split tunneling, so it does not route all traffic, unless you have some special rules.


Thanks,
