Access NAS from WAN thru RED tunnel

vikino over 8 years ago

Hello,

i would like to ask if someone has got some experience in this:

Two UTMs, one with Public IP (Site A), one with private IP (Site B), they are connected with RED tunnel together.

On site A internet traffic is routed oustide via WAN

On site B internet traffic is routed out via WAN

my question is, am i able to reach NAS2 behind UTM at Site B from WAN with Public IP at Site A thru RED tunnel?

Tryied it to set it as Wer server at web server protection, nothing :-/

My thought was to have qnap.domain.com as NAS1 - that works fine

and qnap2.domain.com as NAS2, but this one should route thru tunnel...

Easy it would be when all traffic at Site B is routed thru UTM at Site A, but it is not.

Thanks for any suggestions.

Hi Vitek,

How about a picture of the RED server definition. Also, does doing #1 in Rulz give you any clues?

Cheers - Bob

Hi Bob,

picture of red server is not nesecary, as it is RED tunnel between two UTMs and there is nothing to set up :-) Tunnel is working fine, but im thinking about any nesecarity of masquerading?

Logs are clear.

To be more concrete

UTM A has NAT rule Any-port 8888-WAN NAT to QNAP at site B and service to 8080 - standart QNAP HTTP port, automatic firewall enabled

UTM B has firewall rule Any - 8080 - QNAP site B allow.

" masquerading" - If you need that, Vitek, it's a sign that you have a routing problem that can be handled in other ways, too. From your description, it sounds like you want to replace "Any" in the WAN NAT rule with "Internet" and then choose one of the approaches suggested in Accessing Internal or DMZ Webserver from Internal Network. Any luck with that?

Cheers - Bob
