IPSec site to site tunneling not able to see computers on remote side

Hi NeutralSt8,

have you ticked automatic firewall rules?

If you have ticked can you enable the logging for this rule and show us the log?

Best Regards
DKKDG

Thanks for the reply. Here is the log from the initiator side of the tunnel. Let me know if you need the responder side as well.

I have edited the actual IP's with search and replace but if you need the actual details, I can forward the actual log file that I created. I noticed that there appears to be a number of "whack messages" but I am not sure what may have initiated those comments LOL.

Auto firewall is on and strict routing is not in use - on both sides

I did not change any of the default AES-256 details on either end and had followed the example in the link.

I am still able to remote desktop to the listening side of the site-to-site using the SSL VPN client connection that I had been using before.

However, if I disconnect the SSL client and enable the IPSec site to site, I can no longer ping any of the remote computers.

Any ideas on where the problem may be? Could they be in the Firewall rules and if so, why would it affect the site-to-site but not the SSL client?

Hi NeutralST8,

did you build a new policy as i proposed?

Best Regards
DKKDG

Yes I created a new policy called MyOwn Policy on both routers and the same problem. I can connect but can traverse the network at the listening end. :-(

Sorry meant "can't" not "can"

Hi NeutralSt8,

do you have matches on both firewall logs?

DKKDG

The 2 external addresses (184.xxx.xxx.xx2 and 24.xxx.xxx.xx1) are correct as well as both the declared internal networks.

Not sure what I should be looking for in the firewall logs.

Sorry a bit of a amateur with the debugging. What should I be looking for? When I attempt RDP to my remote server, no entries appear for the IP that I am trying to query.

BTW thanks for the follow up replies

Hi NeutralSt8,

the IPSec log is not needed.
The packetfilter log ist what i meant.

So I finally got a log entry with the desired IP of the system I am trying to RDP to:

2018:10:16-10:52:41 sikanni pluto[18794]: "S_Test IPSec A"[4] 24.xxx.xxx.xx1 #23: cannot respond to IPsec SA request because no connection is known for 192.68.38.250/32===184.xxx.xxx.xx2[184.xxx.xxx.xx2]...24.xxx.xxx.xx1[24.xxx.xxx.xx1]===204.xxx.xxx.0/24
2018:10:16-10:52:41 sikanni pluto[18794]: "S_Test IPSec A"[4] 24.xxx.xxx.xx1 #23: sending encrypted notification INVALID_ID_INFORMATION to 24.xxx.xxx.xx1:500

to get to this stage, I created a direct definition for the host in the IPSec site-to-site settings. At least I am seeing that UTM is looking for the system.

So I created another set of connection definitions and my tunnel appears to be working. However, I am still unable to RDP to the system. I can ping my destination from my local UTM using the Tools - Ping Check.

Where do I go to define the access to the remote computers? Assume my local subnet is 192.168.200.xxx and I am trying to access the remote computers on 192.168.100.xxx?

I would have thought the definitions described in the Remote Gateway(s) would take care of it .. no?

You might try working through #1 in Rulz.

Please show pictures of the Edits of the Remote Gateway and IPsec Connection from both sides.

Cheers - Bob

Yeah, that all looks perfect.  If you did #1 in Rulz, then that just leaves a routing issue.  When you try to RDP to the server, are you using a numeric IP or a name?

Cheers - Bob

I am using an IP address.

What I had been attempting to do was to switch over from the SSL VPN client connection to the IPSec site to site. When I turn off the IPSec, I am still able to connect with the SSL client and RDP to the server. When I switch back to the IPSec connection, I am no longer able to get to RDP to the same system.

Are there routing settings that will interfere with one connection and not the other?

I would have assumed that once the connection(s) is made, the routing would be the same.

I do have some web servers on the Services side (respondent) of the connection that are using the Webserver Protection functions

Pretty generic stuff.

After making another attempt at RDP, I have grabbed a screenshot of the threats on the Dashboard

Opening the Firewall log, a search for 192.168.38.250 shows no entry for that action.

I have looked through Rules 3/3.1 and I can't see anything that would apply to me: don't have 2-NICs on same subnet, have not added any interfaces, as there is only the single WAN and single LAN interface enabled.

The request just seems to go into the ether .. bad joke.

So, are we down to the firewall on the server you're trying to reach?

Cheers - Bob

It seems that way.

So just to confirm:

Site-to-Site IPsec SAs established with settings as shown from office network to services network

RDP connection attempt from office to services network fails

While still site-to-site connected, connect to services network using the Sophos SSL VPN client.

RDP connection to services server is successful.

Disconnect SSL VPN client causes the RDP session to fail.

So how do the routing values change between the 2 connections?

I had been using the SSL client as the primary connection in the past and had always been able to RDP connect to desired computers on the services network.

Thanks again for following up on this.

Cheers,

So I can ping the computer that I am trying to reach from the Initiator side but I cannot reach the computers from the Responder side. I did not think it was necessary to specify a service for the network - as I mentioned, the SSL works without any additional service definitions.

Is that how the connection should work or should the connection be seamless (that is how I expected it once the connection is established)?
