      Ok...So pfsense is 192.168.100.1

      What does the routing table look like on pfsense? Do a traceroute from pfsense for that 172 IP.

              That trace looks odd, are you getting back multiple IPs on the same hop?

              From your trace looks like your problem is upstream of pfsense.. To prove this too yourself - just sniff on wan of pfsense when you ping that IP... Do you see pfsense send the ping request with its public IP as source.. If you do not get an answer that is on your isp or upstream..

                      The site with no result (no ICMP returned) uses an upstream router with differnet settings ?
                      Another ISP ?

                      Also : "Google" uses firewalls. When some networks (read : ISP clients) ping to much, it would not surprises me that Google throttles ICMP a bit for that network. It's just a free service ;)

                        There is a cable modem connected to pfsense that is connected to LAN switch.
                        No another ISP, unless IPsec VPN between sites?

                                  in the vpn, ipsec section - what is setup on the phase 2? This will have tunnel networks and remote networks and local networks defined.

                                        We use 172.18.., 172.19.. on the other site

                                          that is great - then that should reflect the actual cidr for the networks over there - not the whole 172.everything /8 mask.

                                          rfc1918 space for the 172 would be 172.16/12

                                          with that /8 your telling pfsense 172.217 is over there.

                                          If you only have 172.18 and .19 over there then 172.18/15 would be the correct mask
