how to create a VPN between local computers with different network subnets?

Why not use a Site-to-Site tunnel instead of Remote Access?

Cheers - Bob

thank you for you comment, but,

how can the site-to-site solution help me?

i am afraid i am not too familiar with site to site with only one sophos

The solution with Remote Access is very complex.  It will be easier to setup a site-to-site.  If you want to continue about that, please show a simple diagram of the desired topology including obfuscated IPs.

Thank you for the quick comment,

i"m adding a link to the visio diagram that shows what i wish to have in my topology

[Edited]

again,

thank you bob [:)]

P.S
.

I forgot to mention this, my router is dealing 192.168.1.0/24
 , and my Sophos is dealing 192.168.2.0/24 

I'm sorry, but that site isn't trusted. Please Edit that post, delete the link and insert your image into the post. We can't know if that external site is properly protected. The only malware I've gotten in over 10 years was from an external link to a picture in this forum several years ago.

Cheers - Bob

Fair enough,

I have removed the link and i"m posting the image (I might went a little overboard with the "simple" design)

p.s.

for clarification,

the resource image represent 3 different WD my cloud devices.

The "Remote Computer" should be able to access the "Resources" with just a firewall rule in the UTM.  Have you tried that?

Cheers - Bob

[:|] how can i do that? [:|]

P.S.

I am a little bit of a noob when it comes to firewalls (and Sophos) [:$]

Please show a picture of the Interfaces on the 'Interfaces' tab in 'Interfaces & Routing'.

Here you go:

I don't see 192.168.1.1 on your network diagram - is that the IP on ESXi instead of 192.168.1.2?

Cheers - Bob

192.168.1.1 is the IP of my modem/router, the IP that the ESXi has is 192.168.1.2,

the IP of my WAN port of the sophos is 192.168.1.3 (it's D.G. is the router),

the IP of my LAN port of the sophos is 192.168.2.1

192.168.1.1 is the IP of my modem/router, the IP that the ESXi has is 192.168.1.2,

the IP of my WAN port of the sophos is 192.168.1.3 (it's D.G. is the router),

the IP of my LAN port of the sophos is 192.168.2.1
