That would explain the message, as NC uses a larger header to make decoding possible at the receiver side. As far as I can tell from a quick look in packet.h, the required MTU should be 1532 now. (10 bytes unicast + 8 bytes extra for unicast_4addr + 14 ethernet =3D 32 bytes). Or am I bad at counting bytes? // Martin --=20 Kind Regards Martin Hundeb=C3=B8ll Frederiks All=C3=A9 99, 1.th 8000 Aarhus C Denmark +45 61 65 54 61 martin@hundeboll.net --vTrGVHaEIrJMwXTgLuo4KbVEswXDdxrbm Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCgAGBQJS1jH/AAoJEI7EM4tTnYEZYTMQAJNE7Y3jeQq/aqqSuyFhhxp+ GqguhLpMLnnaJv7ryLs4AwTwjDYkyF1msrXnOY83+Y7f1e6GnDaxTs5+oB6t+mrN I6qXUiHSDuuXnYp+m3YBRhOvGZfMIlBifB4ysXQO7bTh29/UI5NfDmNLZtusqmQh RTvmTM+z6SdWVshnLE6Pdgwil0cXVoDLde6KbelH4eI6/JLEdcnD4bmKyX2JRcN0 OiYCeEWgsqZW2TQ2CttE8Ts/2REW0IRQFkOAGsUh3SkxPRhOHC65XTq29UgA0vDi 66ZuuBtLho98db81GpWzlb/qQMFg57tLt2N0vhnI54Kp021zEf3qlb1NJr6SvuZj Wyptl+opVZ0iEDGorBmDv3n5JiNrSY926/NIAvm7lxiGXWTs1uxagmQ34yTVLd3N 3zlvEVNFIPapL6seeaxhqwUn2Hv6/Z6G4EWzZ8sFkA7dZmvIY+mVECvS9PR0NAFr m92U99qjUK4hz7zXtihvU3fCayCTxWLIMMBifcXhPTsvrYaW5fSZQb/y9VTgUeym EwTODM/LOfmqtyEuXGWZbdxZyb/kqL2NaABckkZrbEh/f/t8YhMD0L2/CESrNzpc CnY6YbS7rV61PO9CgZkpkANVJ7h3ZKmwK5ahEkpWDIzml0mqJePVzUlze5TJbPvy Vg//GvD9R7aNx+fBRJUC =bAHz -----END PGP SIGNATURE----- --vTrGVHaEIrJMwXTgLuo4KbVEswXDdxrbm--
