Introduction: I insert a picture of the network connections with the names of the devices named below
I have a routerboard (in picture called rb2) with 4G connectivity with ISP IP under NAT. To reach its interface from the outside I thought to create a PPTP tunnel between it and my main routerboard (in picture called rb1).
I created a PPTP server on rb1 with these parameters (cleaned):
Code: Select all
/ppp profile
add bridge=bridge1 local-address=192.168.3.75 name=hap01
/interface pptp-server server
set enabled=yes
/ip address
add address=192.168.3.75/24 interface=bridge1 network=192.168.3.0
/ppp secret
add local-address=192.168.3.75 name=hap01 password="***************" \
profile=hap01 remote-address=192.168.3.43 routes=\
"192.168.1.0/24 192.168.3.75" service=pptp
set name="rb1"
On rb2 I created a PPTP client with these parameters (cleaned):
Code: Select all
/interface bridge
add name="bridge LAN"
add name="bridge VPN"
/interface pptp-client
add add-default-route=yes connect-to=[rb1 ISP Public IP] disabled=no name=VPN-Client \
password="***************" user=hap01
/ip pool
add name=dhcp_pool1 ranges=192.168.2.100-192.168.2.200
/ip dhcp-server
add address-pool=dhcp_pool1 disabled=no interface="bridge VPN" name=dhcp2
add bridge="bridge VPN" interface=ether4 multicast-router=disabled
add bridge="bridge VPN" interface=ether5 multicast-router=disabled
set name="rb2"
With a pc connected to rb2 LAN (in picture called PC2) trying to ping a device connected to the rb1 LAN (in picture called NAS) it answers and I can access it. From rb1 terminal trying to ping 192.168.3.43 (PPTP interface rb2) it responds, while if I try to ping it from a device under the rb1 LAN (in picture called PC1) it does not respond. I don't even see the IP 192.168.3.43 in the rb1 ARP list.
What am I wrong? I have minimized the exposure of my configurations to avoid confusion. If you need further details on configurations, please ask
Thanks so much everyone
