Re^5: Setting MAC addresses with Net::Frame::Simple

[VinsWorldcom]

I believe your issue is Net::Write::Layer3 while trying to pass an Ethernet header. Try using Net::Write::Layer2 for your $oWrite object.

The frame you're creating ($eth, $ip4, $tcp) works fine for me using Perl Packet Crafter (see Re: Net::RawIP for IPv6) on Windows 7 x64 with Strawberry 5.22.1 x64. On Windows, the Net::Write packages won't install which is why I rolled my own in the form of PPC.

UPDATE:
