Sure.  If your router is running a real operating system, just run:
  arp -a

For example:
  dellbert (192.168.1.11) at 00:02:B3:1E:39:ED [ether] on br0
  xxxxxx (63.249.85.1) at 00:10:67:00:D0:9B [ether] on vlan1
  micron (192.168.1.113) at 00:0F:66:14:E5:4B [ether] on br0
  dellinquent (192.168.1.50) at 00:40:05:C7:1C:44 [ether] on br0
  dellicious (192.168.1.51) at 00:C0:A8:7F:FE:92 [ether] on br0

Hmmm... it doesn't list the LAN side IP address of the router
(192.168.1.1) but that's already known because you can't get the arp
information out of the router without first knowing the router's IP
address.  

I guess we have to use ifconfig, which results in something like this:

br0       Link encap:Ethernet  HWaddr 00:14:BF:B9:10:13
          inet addr:192.168.1.1  Bcast:192.168.1.255 
          Mask:255.255.255.0

br0:0     Link encap:Ethernet  HWaddr 00:14:BF:B9:10:13
          inet addr:169.254.255.1  Bcast:169.254.255.255 
          Mask:255.255.0.0

eth0      Link encap:Ethernet  HWaddr 00:14:BF:B9:10:13

eth1      Link encap:Ethernet  HWaddr 00:14:BF:B9:10:15

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

vlan0     Link encap:Ethernet  HWaddr 00:14:BF:B9:10:13

vlan1     Link encap:Ethernet  HWaddr 00:14:BF:B9:10:14
          inet addr:63.249.85.127  Bcast:63.249.85.255 
          Mask:255.255.255.0

Sorry.  I are not a programmist and don't know anything about
programming.

The MAC address of the router is unique.

If this is some kind of copy protection scheme, methinks you will need
something more sophisticated.  MAC addresses can be spoofed, forged,
or cloned.
