Hi Alan,

I would say, the answer ist 261 bytes:

(1) Sent Access-Challenge Id 68 from to length 0
(1)   EAP-Message = 0x01e803ec0dc0000012f5160303003d020000390303a1b6eb58bf2ce8ab3f12a20eacc792ded76b9714c15bebd6444f574e4752440100c030000011ff01000100000b000403000102001700001603030f7d0b000f79000f760008243082082030820608a0030201020215009613f3945007364d2b46c3df
(1)   Message-Authenticator = 0x00000000000000000000000000000000
(1)   State = 0xfd8b5894fc6355beb76ffb2667a966eb
(1) Finished request

Or do I understand wrong?

  Did you check that the EAP-Message attributes were about "fragment_size" in length?

  Did you check that the Access-Challenge packet is less than 1500 bytes in length?  This *IS* printed in the debug output.

  There is no magic here.  If the packets are larger than 1500 bytes, then something is making them larger than 1500 bytes.

  Since you're not posting the debug output, there's little more we can do to help.
