Unknown Connection

Router WRT54G Linksys (with DD-WRT Firmware)

In my syslog i have following:

8 12:03:44 I udp 10.34.107.25 67 255.255.255.255 68
2007/03/18 12:03:44 I udp 10.34.107.25 67 255.255.255.255 68

I had this connection with Hyperwrt too!
Always denied and Service "bootpc" it was mentioned ...

ping and tracert to the ip is not possible, it times out ...

IP is a private one, so ripe unuseful ...

Is this another router?

Following to port it is:

68/tcp bootpc Bootstrap Protocol Client
68/udp bootpc Bootstrap Protocol Client

Connected is only one pc and sometimes my notebook ... (pc mostly
turned off then)

There is no security aspect here. This is just a BootP request on a local, non-routable,
sub-net.

Futher queries should be made in a TCP/IP related News Group to understand Private Addresses
and the BootP Protocol.

So it can't be a wireless hacker?
My Router has local and wireless LAN connection ...
internal IPs start with 192.168. ....
that's why i was wondering ...

If you are using wireless then it may be a remote platform trying to obtain an IP from the
Router. Since it is the WRONG network, it will go nowhwere.

TCP/UDP port 67 & 68 are used BootP/BootPS hich is the older way of obtainuing an IP address
which was replaced with DHCP.

If you want to increase wireless security, make sure that the Router will only assign
addresses to provided MAC addresses.

I know that it is ;-)
The question where does it come from?
I only see the Wireless Networks (about 7 Routers and 2 Laptops seen),
but it seems strange to me, that i see an IP in my denied Log ...

My LAN IP starts with 192.168
Provider IP with 80.109 ...

So i am wondering from where the IP is ...
Wireless or Provider?
Tracert/ping are not possible

Thats why i thought maybe security thing ;-)

WPE 128 + Mac only assigned is set ;-)

Is it still possible to come a network, if both are set?
