Packets from Martian source

I've read issues of D-link routers causing the issues with invalid IP addresses. Maybe just updating the firmware on the router would be enough.

Could it be that someones phone is trying to connect to a service, but is incorrectly configured?

It's a pain, but block all the MAC addresses and then let them through one at a time and see which one throws up the error.

Dunno if this is related Uldis, but I found this while browsing my ISP's support forums. It appears that certain Android versions can exhibit DHCP-related "bugs". As I haven't a clue what a "Martian source" packet is I'm simply throwing this in to the mix on the off-chance it's useful to you.
