      Is there some fuction which would prvent the reachability from one site from a site to site vpn to the other as long as there is no initiation from the other side?
      I have some strange problem: I've configures an ipsec site-to-site vpn. Configured a route from one network to the other with a specific route 192.168.51.20/24 via 10.0.0.254 on a 10.0.0.128/25 net and a 10.0.0.128/25 via 192.168.51.248.
      My problem now is when I try to reach the 10.0.0.161-166 from 192.168.51.20, 10.0.0.161 is reachable all the time as well as both vpn gateways, but from 162/3/6 I got no response at the first attempt.
      now 162/3 are working constantly but and 165/166 is still not reachable
      but as soon as I ping 166/165 from 192.168.51.248/10.0.0.254 or from 10.0.0.166 the 192.168.51.20 it does work but only as long as the ping is going on.
      As soon as I stop the other ping it take one minute and the ping stops again
      Can someone give me a hint how to find out what could be the problem
      I've tried tcpdump but I get no sensible information
      The icmp request just start from one side and just gots no response
      At first I thought it might have something to do with both sides being vm's on vmware basis but then I found out that specific systems which are not vm's are behaving the same way. Since 166 is a VM and 165 is physical.

      here are my routes:

      I've configured a "any" to "any" firewall rule for each pfsense interface and box.
      Just to be sure it's no firewall thing.

      I hope someone can help me to find this problem.
      Thank you in advance.
