The connection is established through ppp with the dial-on-demmand capability. The machine also serves two incomming dialup lines, supporting SLIP and PPP connections. This box routes IP packets between two ethernet LAN's, between the network hosts and the Internet, and between the PPP/SLIP hosts and the all the computers. Sometimes, on heavy traffic, I get the following message: No buffer space available I would like to build a new kernel, with the TCP/IP tables and buffers optimized for this kind of processing. Is there any way for this to be done ? What should I change in the kernel files ? Thanks in advance, Joao Cabral.
