Inter vlan communication

  • Hey I'm having some issues with trying to get 2 vlans to communicate.

    I have Lan and Vlan101.  I do have other Vlans which are working properly.  But with my newly created VLAN101, I can ping from VLAN101 to Lan.  But cannot Pint from Lan to VLAN101

    I think I got the rules set properly but i'm pretty sure its a firewall issue.  I turned off Symantec fully and disabled windows firewall.

    I also Included Vlan31 screen which works.

    I can ping the DG of the vlan101 from LAN, but not anything inside the vlan101.  DHCP works and vlan101 can get internet access.

    Any help would be appreciated,

    Your interface address should not be inside the DHCP Pool.

  • Fixed it, but that wasnt the problem.

    total of 4 devices on that vlan

    looks ok to me..  So your saying you can ping lan devices from vlan101, but not from lan to vlan101

    I would really look to the client on vlan101..  Do a sniff, does pfsense send the icmp to the client..

    Rules look fine..

  • ok I got it fixed.  Was really weird

    Might have been some setting didn't get saved properly.

    I changed the network to .131.* thinking maybe there is something wonky.

    it worked….

    then I changed it back and it was working?????.  o well I wont kick a gift horse in the mouth
