Accessing shared folders over IPSec Site to site VPN
I have 1 ATP200 and 1 USG flex 100 connected with a wizard-created IPSec site-to-site VPN. Both devices show the VPN as connected with a green globe.but we cannt access or ping to each other from office 1 to office 2 or office 2 to office 1.
we tried \\192.xx.xx\folder and \\pcname\folder and nothing and ping does not work either!
we have been trying for 1 week and nothing helped. thank you
Purpose:1 pc from office 1 has the shared folders that people from office 2 need to acces!
usg flex 100 is connected tot the router(ex: 84.212.36.16) and that is where he gets internet from (lan2) .
i did put DMZ on USG so there will be no firewall rules blocking VPN and i did alsaw open ports (portforwarding):
• UDP 500 ‘Port based Rule’ (IKE)
• UDP 4500 ‘Port based Rule’ (NAT traversal)
Office 1: Router ->> USG100 ->>> PC(shared folders) (Public IP: 84.212.36.16)
Office 2: Router ->> ATP200 ->>> computers (Public IP: 215.62.33.11)
===================================
Office 1 (USG flex 100):
===================================
Public IP router: (ex: 84.212.36.16)
WAN (DHCP) : 10.0.0.25
LAN2 STATIC: 192.168.2.1 / 255.255.255.0
PC with the shared folders IP: 192.168.2.33
===================================
Office 2 (ATP200):
===================================
Public IP router: (ex: 215.62.33.11)
WAN1 (DHCP) : 192.168.3.4 LAN1
STATIC: 192.168.1.1 / 255.255.255.0
=================================

I have tested to add more ports to services to make it work but nothing happend1 i have alsaw not added any policy rule!!

Add the follow routing rules at the top of then list
office2
incoming LAN1
destination subnet 192.168.2.0 / 255.255.255.0
next hop
type VPN Tunnel
IPSec_VPN
office1
incoming LAN2
destination subnet 192.168.1.0 / 255.255.255.0

Have you tested the shared folder on the same network?
Windows firewall might be blocking it
test by
\\192.168.2.33

thank you for your respond. ☺️
the computers in office 1 can acces the shared folders and we turned off the windows defender/firewall off from both sites/offices.0 -
I am pretty sure you need to create a policy rule to allow the packets to travel from LAN on one side over to the connection link. I don't remember the exact details, but I believe you need to add the policy rules on both sides, allowing NetBIOS traffic to go through the VPN connection.

Try to enable NetBIOS broadacst over IPSec on both devices and you should be able to access the shared folder are the remote site by IP address without extra policy routes. Here are some examples.

Site to site is connected and Enabling NetBIOS broadcast on both devices. still not able to ping or acces shared folders . any idea's for policy control or routing rules that should be added.
thank you0 -
By default windows will not allow another subnet to access a shared folder there are two ways around this but as to have disable the windows firewall this is likely but the problem.
You need and firewall rule on Office 2
from LAN1
to IPSec_VPN
You need and firewall rule on Office 1

To ping from office1 to office2 you need
firewall rule on Office 2
from IPSec_VPN
to LAN1
firewall rule on Office 1
from LAN2
to IPSec_VPN
I don't get why you can't ping from office2 to office1
do you get logs in office 1?
