IOS firewall loging

Hi, communication over IOS firewall sometimes drop one or two packets in tcp protocols, the same packet sometimes repeat more times until it dies.

Access list are in my opinion all right, I use both extended access list and CBAC, everythings works as expected however, I have a lot of those lonely packets in my syslog. Is there any option how to reveal what packets they are ? I have only this info in my log - list XY denied tcp src_addr(src_port) -> dst_addr(dst_port), 1 packet.

However no info about possible flags in packets, no additional info ? Does anyone how any tips how to found out what packets they are ? Thanks a lot.

Re: IOS firewall loging

You might be overworking your router with too much traffic if you're getting a lot of packet loss.
