PIX Firewall MAC address VPN IP address

Discussion in 'Cisco' started by Julian Dragut, Feb 7, 2006.

  1. Hi there,

    Would it be possible for a PIX 515e to have IP address reservation for the
    VPN users based on the MAC address of the remote user?

    Thank you,

  2. Not in PIX 6.x, and I would think it unlikely in PIX 7.0.

    IPSec encapsulates content at the IP level, and the IP level
    does not include MAC addresses.

    If there is any way to get at the MAC address in PIX 6.x, it would have
    to be via RADIUS or TACACS+ -- I don't know what information is
    potentially available for them. It doesn't matter in PIX 6.x
    as RADIUS and TACACS+ cannot be used for IP selection in PIX 6.x.

    PIX 7.0 does not appear to support EAP or LEAP authentication.
    It does support LDAP; I don't know if LDAP carries the MAC as one
    of the attributes. I wouldn't -expect- IP addresses to be selectable
    that way anyhow.
