Arp Statement



  • guys i have a proxy arp entry on an existing router, if you guys could help me port it over to pfsense, that would be awesome. Below is everything from the old router, Ive stripped down the actual IP addresses for safety.

    (IP address "A.A.A.A/32" on LAN interface with gateway "B.B.B.B" responds to ARP requests from WAN)

    I already created the virtual IP ARP but i don't know where to add in the B.B.B.B part. Is it something to do with 1:1 NAT?



  • also…
    here are my current pfsense settings.
    under Firewall > Virtual IPs > (the P ARP statement that i made)

    (Type Radio choices) Proxy ARP
    (Interface) LAN
    (IP Addresses, Type) Single Address
    (IP Addresses, Address) A.A.A.A

    no virtual ip password



  • Either 1:1 NAT or portforwards will work. Don't forget to create pass firewallrules for this too.



  • ok i created the following 1:1 NAT rule, is this right?

    Interface WAN
    External Subnet B.B.B.B/32
    Internal Subnet A.A.A.A



  • @ghetek:

    (Type Radio choices) Proxy ARP
    (Interface) LAN
    (IP Addresses, Type) Single Address
    (IP Addresses, Address) A.A.A.A

    Not sure, something is wrong, either that your ProxyARP IP is at interface LAN or youe 1:1 NAT. You are still missing a firewallrule to allow some traffic too.



  • here is the EXACT arp statement as it is on the existing router, this is what i need to put into pfsense to replace that existing router.
    –--------------------------------
    IP Address/Bitmask
    A.A.A.A/32

    On Interface
    LAN

    Proxy on Interface
    WAN

    Gateway
    B.B.B.B

    On the existing router there is no mention whatsoever of either A.A.A.A or B.B.B.B in the NAT area. I hope this helps clear things up, and thank you so much for your help so far.
