Allowing random IP/PORT into LAN

SteveITS

@wwdot_computers Datto would be on your network so is not related to pfSense, because traffic between PCs on the same interface doesn't go through the gateway. They mean, open that port in the Windows firewall.

johnpoz

@wwdot_computers if you want port 25568 that hits you public facing interface (wan) to get forward to some inside machine say 192.168.1.100 that would just be a port forward.

That and then the associated firewall rule that the port forward can auto create for you.. Just need to make sure the rule is in the correct place on your wan so some other rule you might have placed there doesn't block the traffic your trying to allow.

edit: if this is machine A talking to B that are on the same network - as @SteveITS mentions pfsense has nothing to do with that traffic.

@SteveITS @johnpoz

So the agent is on multiple machines on the LAN. They talk back to Datto servers for backup. We do not have an in-house appliance that we are backing up to, it is strictly a cloud backup. I guess I am asking how do I open up the port for the entire network or a pool of computers?

johnpoz

@wwdot_computers but that is outbound traffic - you would have to adjust your rules to allow for the traffic.. So you see that blocked.. By default default deny is logged.. So if your rules do not allow these to talk to something in the cloud, ie the internet then one of your rules is not allowing it.

Did you inherit this set of rules? I would assume someone that created all those would understand how to allow something else..

You say this is inbound

Inbound connectivity on the protected machine:
TCP port 25568 (for Datto Windows Agent service)

I find it highly unlikely that some service you backup to in the cloud would need unsolicited inbound traffic from the internet to some machine behind pfsense.. But that would be a port forward.

@SteveITS
It was a joint effort? Under guidence I created the rules. However the person that helped is no longer able to do so. Long story.

Would you suggest going back through the rules and starting over?

So the inbound connection:

Inbound connectivity on the protected machine:
TCP port 25568 (for Datto Windows Agent service)

Is really outbound? How does that track? It seems that they are requesting an inbound connection?

johnpoz

@wwdot_computers see my edit.. I have never heard of some backup service to the cloud that would require you to open a port from the internet to your server your backing up - that makes no sense at all.

Unless you have turned off default deny logging that is logged, and your last reject rule is set to log - so if pfsense blocked something from it would be logged

Sorry wrong person

How do I see the edit? New to the forum as well.

Here is the KB:

Datto runs on a backup device in the office and backs up PCs in the office. "on the protected machine" is each PC in the office.

@SteveITS

No, I get what it is saying. We do not have the appliance though and each system has an agent installed on it. The agent talks back to the Datto cloud for backup.

I hope that I am making sense.

johnpoz

@wwdot_computers that screams the local firewall on the device your running that agent, not from the internet.. Since that makes zero sense at all that you would have to make

Here is a drawing on their site..

See the local network cloud.. This siris box talking to your protected box... So unless this box is on some other vlan in your local network than the protected machine.. There is no firewall rules needed in pfsense.. But the protected machines local host firewall would have to all that traffic.

You linked the Datto BCDR backup which AFAIK is only via an on site device, either Alto or Sirus.

Do you have Endpoint Backup?

(or others going down the left menu on that page)

wwdot_computers

@johnpoz

That is an inaccurate representation of our setup as we do not have a Siris box or any other for that mater. Each machine needs to connect to the internet directly for the backup. All of the machines are not able to connect, so I do not think it is a local machine firewall issue.

wwdot_computers

@SteveITS

That is correct. We have the Datto Endpoint Backup
Endpoint Backup is our fully cloud-based backup and recovery solution for Windows Servers or PCs. You can leverage its features to restore single files or the entire backup image to a new device without any extra equipment required. Select a topic from the left navigation pane to continue.

I am not sure why the tech support linked me that other link. Sorry, was just not looking. However, that being the case, still have the issue :(

Looking at that KB, which I should have caught the first time around, there is not an inbound. I have opened the appropriate ports of outbound, but in the logs, it seems to block 587/443 and such.

Ideas?

johnpoz

@wwdot_computers yeah open the ports they list outbound - no where in that list does it say anything about the port you were listing.

There is also that 3262 port, but that seems to only be needed for bare metal restore.

edit: most of these rules make zero sense if you have endpoint only

Those ports are not listed in their doc, what do you have in the alias?

edit2: As a troubleshooting tool, create a rule on the top that allows one of your machines your trying to backup any any.. Log its traffic - what ports does it talk on for talking to backup?

Maybe your issue is dns related? And it can't resolve what that list says it needs to be able to resolve.. But looks like it need only 443 outbound, and then one of those 3 ports.

wwdot_computers

@johnpoz

Here are the ports in the alias that I have from the rules I posted prior:

johnpoz

@wwdot_computers

Well that 3260 and 25xxx ports are not needed per their doc.. And 123 is ntp and wouldn't be tcp, that would be udp.. And while sure the box should sync time it wouldn't do it over tcp.. And it can get time just from pfsense ntp server.. There doc doesn't list that as a requirement that I saw..

Maybe your issue dns related? Validate you can resolve those listed fqdn at the host your trying to backup.

wwdot_computers

@johnpoz

Interesting. Can not resolve "dattolocal.net" Ideas?
