You could use a custom ip chain. Add a rule to forward matching packets (such as all packets with a source port of 5001) to this chain. Then just simply add a "return" line in the chain itself. Chains automatically track bytes/packets so you could easily keep tabs that way. On 16 Mar 2005 at 9:46, M. A.
