Colleagues, please help i cannot understand the situation.
I have configured an IPv4 tunnel from Host A to host B
all configs on both sides are identical.
So, what happen exactly Ipsec is connected and all working fine accept that it`s working one way only,
like from side A to B all good (all services are working) from side B (Nothing work) no ping no RDP!
and the most interesting thing it goes down but on IPsec=>Status overview all good
what can it be?
Firewall rules on the LAN interfaces of both locations, please.
Hi
if the IPsec tunnel is up and connected this sounds more like a routing issue.
I am assuming side A is a completely different subnet to side B?
On both sides have you checked the routing table such that the device on side B has a route to the subnet on side A, and visa versa the device on side A has a route to the subnet on side B?
IPsec rules
Protocol Source Port Destination Port Gateway
IPv4 ICMP * * * wan_gateway
IPv4 TCP/UDP * * * wan_gateway
IPv4 * IPsec net * * * wan_gateway
LAN rules
Default
WAN
Protocol Source Port Destination Port
IPv4 ESP IPsec net * WAN address *
IPv4 TCP/UDP IPsec net * WAN address 500 (ISAKMP)
IPv4 TCP/UDP IPsec net * WAN address 4500 (IPsec NAT-T)
Maybe its a similar issue like I had in the past.

Are the communication endpoints on dedicated clients or on the VPN endpoints (opnsense) itself?
Thanks for answer yeah maybe you are right.
but i manage to make it work and when i changed the server hardware the appeared once more.
