VLAN help with netgear smart switch

  • Hi guys I am after some help here, I have been racking my brains and it is probably something simple I have missed. Sorry this is going to be a long post but I will try and put as much detail in as possible.

    I have just bought a Netgear GS105Ev3 smart switch to try and get my home network vlanned to secure and separate things like media, office etc.

    I have configured the switch as follows through the VLAN 802.1Q settings:
    vlan 02 has port 2 untagged and port 1 tagged
    vlan 03 has port 3 untagged and port 1 tagged
    vlan 04 has port 4 untagged and port 1 tagged

    Port 1 connects to the PfSense LAN port. I will add screenshots of my config pages as attachments.

    I think the switch is configured correctly because when I set the VLANs up on PfSense I get the correct IP address for each port on the switch.

    My LAN is on, VLAN02 is on, VLAN03 is on etc with PfSense handeling all the DHCP. If I plug my laptop into port 2 on the switch i get a IP address, I am able to reach the switch which is on and my PfSense box on but I cannot get internet access.

    I created a firewall rule under VLAN02:
    allow : IPV4 protocol, source is VLAN02 net destination any any

    I am only guessing but as I can reach the switch and PfSense box when plugged into VLAN02 and get the correct .20 address it is likely to be a rule issue, which is why i created the above rule. Still no internet access.

    Any help is greatly appreciated. I have attached a few screenshots of my config pages if it helps.

    Why the leading zeroes on the VLAN tags?

    That rule on VLAN02 looks fine. About the only thing preventing internet access would be lack of outbound NAT. Did you set manual/advanced mode there?

  • I can't remember the reason for the leading zeros. There must have been a reason.

    I have manual NAT outbound rules in place as attached which I thought would be right?

    No. All of your outbound NAT rules should be on WAN. Is OPT1 a WAN? Is there a gateway set on the OPT1 interface configuration? If so there probably should not be. If you have multi-wan then everything is fine except the source networks.

    You need Outbound NAT rules on WAN for all of your source networks,, You might just want to re-enable auto NAT mode (the default which you decided to change for some reason) and all of this will probably just start working.

  • OPT1 is my VPN which originally had my LAN going through. Eventually, only specific VLANS will use the VPN and the rest will go straight through the WAN.

  • LAYER 8 Netgate

    OK. A client connection to a VPN provider should be considered a WAN and treated like a WAN.

  • Cheers. I knew it would be something simple I missed. Had to put the outbound rule for the VLAN for OPT1.

    Now it's all working. As soon as I type the last reply I realised my error. Sometimes it just needs a fresh pair of eyes.
