I've tried the access list:
Access-list 110 deny ip host 127.0.0.1 172.30.1.0 0.0.0.255
Access-list 110 permit ip any any
applied to the inner interface on the router.
Ip access-group 110 out
Didn't help, the packets in question still arrives. The funny part is, I
have WireShark installed on both hosts, and whatever host I'm sniffing from,
that host's packets shows up correctly while packets to/from the other host
generates packets from 127.0.0.1 *with the same DEC MAC addresses*
Probably a simple explanation, but...
Way beyon me

Do these packets (127.0.0.1) arrive via the router or are they from a
machine
on the local subnet? To find out, just put an access-list on the router,
denying packets with source 127.0.0.1 (don't forget a "log-input") and check
whether the counter increases (and log messages).

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
