      Ok. So, nothing appears on the LAN interface. So, it should be a firewalling problem… Do you have any rule which permits traffic from your LAN to the Netasq LAN?

      Last, I suppose there is no route for the range 192.168.50.x on the Netasq. I mean: this range is not known by the Netasq except for your IPSEC tunnel.

        I have a rule that passAll on IPSec interface from any -> "networks internals" (LAN range)
        Do you think it's necessary a static route for 192.168.50.x range?
        Thank again for your help!

          You don't need to add a route except if the IPsec is configured to "consider IPsec peer as internal". If IPsec is configured like that, you need to add a static route pointing to interface IPsec.

          By the way, can you send a screenshot of the firewall rules on the Netasq?

          I'll be unavailable for 1 hour.

            Ok, thanks!

            This are the first 15 rules…

            Rule number 12 it's this VPN.
            Rule from 5 to 11 it's others (worked!) VPN...

              Ok… The point is that you need to be authenticated on the Netasq before your traffic is allowed. This is the @ in the source column...

              So, either you change that to get rid of the authentication. Either you authenticate yourself on the Netasq web interface...

              Well, as we speak about IPSec tunnel, I strongly recommend to disable the authentication for those traffic (as traffics are already trusted).

                Oh YES!
                That work!

                The problem is in the rule 12, I modify the rule so I permit traffic from 192.168.50.0 to Networks internal and now it worked!!!

                MANY THANKS guys!

                  Great news but as said in my previous post, I strongly recommends 2 things for IPSec filtering:

                  • disable authentication for IPSec tunnel as those traffic are already trusted. Except if you need authentication for HTTP proxy for example.

                  • use network object (as you've done for your tunnel) for each tunnel…

                    Disable auth.: I must disabled auth. also for IPsec mobile connection?

                    Thanks…

                      Well… Actually, I don't know why you use Authentication for VPN tunnel (rules 5 to 11)... Normally, It's not necessary... But If you do that, you'll need to configure network objects defining all your remote networks in order to avoir security holes... Do you see what I mean?

                        Yes, I understand.

                        I use this particular configuration (made with netasq support) for consent access from outside for some customer that needed access on particular server inside LAN.
                        Authentication VPN from <<any>> host it's (i think) only method to obtain the goal.
                        In particular I have a rule for every mobile access and i pass all traffic only to a host.

                        In you opinion it is a flaw in security?

                        Thanks…</any>

                          Ok… You're in an exception and this is not a security hole.
                          If you use only "any" as source, it could be a security hole but not with authentication.

                          BTW, good news your tunnel is working.
