      Hi,

      Can't seem to be able to reach internet or other ips from an interface vlan (100), while everything works for LAN (VLAN10).

      Firewall and Gateway/Routing should be ok, Outboud NAT also seems ok... What else should I look at? The device has the right gateway set.

      Both pinging 8.8.8.8 and google,com give

      ping: connect: Network is unreachable
      

      So something is amiss...

        @urbaman75 Check your logs. Status->System Log click on Firewall, look for your ICMP.

          Hi,

          Another quirk.

          I am trying to ssh from LAN (vlan10) to management (vlan100).

          In the firewall log I see

          Jan 22 21:23:32	VLAN10	Default deny rule IPv4 (1000000103)	  10.0.10.37:58066	  10.0.100.11:22	TCP:PA
          

          Already added the rule(s) (also directly from the Firewall log) to permit it, but the firewall still stops them:

          VLAN10 Rules:

          VLAN100 Rules:

            Ok, first problem solved: the device did not have the default route, don't know why it did not apply it.

            Second problem remains. trying to reach intervlan connections...

              @urbaman75 I start with simple things... ping the IP from the other IP. If it fails... Check the logs.

                I can ping, can also ssh to it for some seconds, then the connection is closed, with the aforementioned deny rule in the logs...

                  Your rules are all screwed up.
                  The network attached to an interface is the only thing that can be a source on that interface.
                  So on vlan 10 you have a 10.152.183.1 address as source, with the vlan 10 as destination. It's on the vlan 10 interface, vlan 10 can't be a destination if you're already there!

                  Same with vlan 100.
                  Read up on how rules are evaluated.
                  It'll explain why you have those 0/0's next to rules.

                    @jarhead thank you, I properly setup routing, gateway and everything else.
                    Now I have a different problem but probably I'll make another dedicated post.
