Arp fails?



  • hi everyone,

    i’m new. i just put pfsense in front of a cisco 2811 router, which is in front of a 3750 switch. i can access the internet but devices on the internal network don’t seem to be arping to the router (except 1). i’ve tried arping from some devices and they don’t work. pfsense is dhcp on the wan side, 192.168.5.1 on the lan side. the router fa0/0 (wan) is plugged into the lan side of the fw with an address of 192.168.5.2, and fa0/1 (lan) is configured with 192.168.10.1. i have a route on the router with quad zeroes to 192.168.5.1, which is probably part of the problem. i have route on the fw for 192.168.10.0/24 through 192.168.5.2.

    i’m on a mobile so i can’t attach my switch/router config but if it’s needed i will when i get back to my desk.

    update: added router/switch config
    router-config.txt
    switch-config.txt

    There's the problem.  You can't have the same network on both sides of a router.



  • i reloaded the switch and router, rebooted all the servers and the app tables populated appropriately. thanks!
