DHCP Discover packets are dropped by Satellite Gateway in Star community after VPN is established Technical Level
Symptoms
  • Satellite Gateway in VPN Star community drops DHCP Discover packets (sent from IP 0.0.0.0 to IP 255.255.255.255) when "VPN Routing" in community properties is set to "To center, or through the center to other satellites, to internet and other VPN targets".

  • DHCP Discover packets pass correctly when "VPN Routing" in community properties is set to "To center and to other satellites through center".

  • Example topology:
    DHCP Server --- [Center Gateway] === VPN === [Satellite Gateway] --- DHCP Client

  • Office Mode DHCP Requests fail when sent over VPN Site-to-Site tunnel.

  • SmartView Tracker log shows:

    "Connection Failed: You cannot receive an Office Mode IP address at this time. Try to connect again. If the problem persists, contact your administrator."
  • DHCP Request is traversing the VPN tunnel as expected; DHCP Offer comes back from the DHCP server, but is not handled properly by the Security Gateway.
