acl arp в squid

[C S <ll755ll@yandex.ua>]

День добрый,

в squid.conf указано:

"#       acl aclname arp      mac-address ... (xx:xx:xx:xx:xx:xx notation)                           
#         # The arp ACL requires the special configure option --enable-arp-acl.                     
#         # Furthermore, the ARP ACL code is not portable to all operating systems.                 
#         # It works on Linux, Solaris, Windows, FreeBSD, and some                                  
#         # other *BSD variants.                                                                    
#         # [fast]                                                                                  
#         #                                                                                         
#         # NOTE: Squid can only determine the MAC address for clients that are on                  
#         # the same subnet. If the client is on a different subnet,                                
#         # then Squid cannot find out its MAC address.             "

т.е. сквид на основе макадресов может работать с аксесс-листом для хостов, находящихся в той же подсети...
Нет ли какого-нибудь способа обойти ограничение?
