Hi.. It was a bug in my port due to heavy changes i made on the stack because my misalignment problems. I have fixed it and the bug had nothing to do with lwIP standard stack. Sorry for the inconvenience..

The Ethernet driver is one that I wrote myself. Version of lwip is 1.3.0 when it was first released. (not RCs). I use the socket API to send and recv data. Do i have to do connect as a UDP client ? I am now debugging to check if the Ip address was corrupted in anyways either in PCB or in the IP layer. If i find anything ill definitely write it in here.. > Subject: RE: [lwip-users] Routing error in lwip 1.3.0 > From: address@hidden > To: address@hidden > Date: Thu, 10 Jul 2008 13:43:42 +0100 > > On Thu, 2008-07-10 at 12:40 +0000, Muhamad Ikhwan Ismail wrote: > > > > Hi, > > > > Ill try to simplify a bit here : > > > > 1.
