General Questions / Can ping one way but not the other
« on: March 06, 2018, 01:22:12 pm »
Hello I am having issues with IP communication between two interfaces in a bridge. I have followed this guide right here to set up the bridge: Right now I have a LAN interface doing VLAN 20 tagging bridged with an OpenVPN interface to allow layer2 TAP communication. The LAN interface has the IP address DHCP is configured correctly and all devices on the LAN as well as the OpenVPN are getting IPs from the DHCP server. From inside the LAN all devices can communicate with each other and they can ping the gateway. However from the client connected to OpenVPN I can ping the gateway but I cannot ping any other device on the LAN. And from the pfSense I cannot ping the OpenVPN client. I am stumped and cannot figure out why this is not working.

OpenVPN / OpenVPN bridged with LAN VLAN issues
« on: March 05, 2018, 06:15:26 pm »
I am trying to bridge my OpenVPN L2 TAP (not Tunnel) with my LAN VLAN. That part works fine and my devices are able to get an IP address however when I VPN in I am able to ping the gateway IP address which is assigned to the bridge interface however any devices on the VLAN are not able to ping the gateway. After reviewing the packet logs I notice there are a lot of ARP request going to the pfSense and the pfSense is replying but it seems to me that the switch is not getting those replies on the trunk interface. The set up I have is the pfSense as a vmware appliance with the interface trunked to my Cisco switch with VLANS for LAN, MGMT and Guest users. MGMT and Guest users work fine because they are not linked to a bridge and LAN was working before but the moment I linked it to the bridge and reassigned the IP to the bridge interface my LAN network no longer works. I am stumped and am out of ideas. Can any of you guys help me out with this?

Illustration01: Here I am able to ping the bridge IP from a device logged into OpenVPN.
Illustration02: From here I am able to ping a device on the LAN from the Switch sourcing an Switch Virtual Interface.
Illustration03: However here I cannot ping a device on the LAN from a device connected to the OpenVPN.
Illustration04: And here no device on the LAN can ping the Bridge IP address.

Packages / FreeRADUIS not Authenticating with PFSense using OTP
« on: October 23, 2017, 10:39:19 am »
Hello I am having issues with FreeRADUIS in that when you go to Diagnostic > Authentication it keeps failing whenever I use an account with OTP. However it works fine with static passwords. On the same token I have a Cisco switch that is authenticating with FreeRADIUS as well and that has no problem authenticating with OTP. Why is it that I can authenticate fine using OTP on a Cisco switch but it fails on pfSense?
