Passing traffic between a remote access VPN and Site-to-site VPN on an Edge Router Lite

So what happens when you ping domain.com?

The final challenge hasn't been solved yet. When connected to the remote access VPN, I can access a file share using \servername\sharename; however, I cannot access the file share using my DFS namespace \domain.com\shares\sharename. I created our DFS namespace a few years ago when I deployed AD, during my dark ages of not truly knowing what I was doing, so the DFS + VPN issue should likely be another thread.

Likely a DNS issue. How are your VPN users resolving \servername today? Do you have hosts entries? or are you pushing DNS entries along with the IP for the VPN connection?

They're getting a DNS server along with the IP when they connect on the VPN. That DNS server is our domain controller. On the client computer, I've also configured a DNS suffix on the VPN's network adapter.

Could be offline files being enabled because of the slow VPN link. Windows 10?

@wirestyle22 That make sense. As this looks like it "resolves" \\domain.com\shares\pathToFolderRedirection, yet \\domain.com\shares\someOtherShare fails.

@eddiejennings Control Panel > Sync Center > Manage Offline Files > Disable Offline Files

Test that just to see. You will need to reboot.

That seemed to work. Enabling it again prevented me from accessing DFS shares.

Couldn't find a host.

The next challenge was being able to access the colo's ERL from the office. To do this, I had to add a rule to the WAN_LOCAL ruleset on the Colo's ERL, to allow traffic tp TCP 22 and 443 from 192.168.2.0/24. I had to do the same for 192.168.1.0/24.

Or you could just allow new from IPSEC packets.

jbusch@jared:~$ show configuration commands firewall | grep "rule 40"
set firewall name WAN_LOCAL rule 40 action accept
set firewall name WAN_LOCAL rule 40 description 'Allow IPSEC'
set firewall name WAN_LOCAL rule 40 ipsec match-ipsec
set firewall name WAN_LOCAL rule 40 log disable
set firewall name WAN_LOCAL rule 40 protocol all
set firewall name WAN_LOCAL rule 40 state established disable
set firewall name WAN_LOCAL rule 40 state invalid disable
set firewall name WAN_LOCAL rule 40 state new enable
set firewall name WAN_LOCAL rule 40 state related disable

@EddieJennings did you resolve your issue?

Most likely so. It appears that offline files is the clue I needed. I can do some more testing tomorrow.

YOu don't use Offline files though right?

[Dashrender]

It seems odd that performance would be an issue here. When accessing files you want the most live, up to date files, so as long as you have access, you should be getting them from the server.

What am I missing here.

I do. For the internal office people, the main profile folders (Desktop, Documents, etc.) are redirected to network storage. When you have folder redirection, I believe Offline files are enabled by default.

They are, but they don't have to be.

Okay, but you don't have to have Offline files enabled, do you have users coming in and out with laptops from officess?

Yes, me.
The folks who have laptops and occasionally come into the office, don't have folder redirection enabled. I'm the only person who would be affected by this; thus, I think my work around will just be using UNC paths if I need to get to file shares when I'm at home and connected to the VPN.

Now you've lost me. I didn't really understand your earlier thing either between the two different UNCs you posted - can you expand up on that?

[EddieJennings]

@dashrender Yes. When I'm connected to the remote access VPN and Offline files are enabled, this condition occurs.

\\mydomain.com\shares\theITDeptShare fails.
\\serverName\theITDeptShare works.

Right, so the question is - why is your machine not resolving mydomain.com?

You could likely easily solve this with a host file entry for mydomain.com (though perhaps not if the IP stack doesn't see mydomain.com as a valid host name, not sure).

I guess it does work
