That highly depends on the type of protocol you want to use... Some protocols can be implemented using a new netif driver, some have to pass their structures trough UDP an IP again (and that might not be supported out-of-the-boxx by lwIP). > At least, how many ressources must be available for such an extension? Again, that highly depends on the protocol. Keeping control structures aside, the main resource burner will be encryption (if used). Also, the protocol overhead will be bigger because now, additional headers will travel through the line and thus, user data per packet will be smaller. > Any thoughts are highly appreciated ... ;-) Depending on your requirements, you might want to consider using a tunnel protocol (like PPTP, I think) instead of using a full featured VPN protocol (like IPSec). However, I haven't implemented any of them, so I cannot tell which is the easiest :-) > Simon _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
