Hi, In the ACK-matching example in the LARTC-HOWTO there is a line to match all packets smaller than 64 bytes ("match u16 0x0000 0xffc0 at 2"). This sounds logical for Ethernet-devices, but what if I use a PPP-device (as it is shown in the example)? The Frame-Header of PPP is significant smaller than the header of Ethernet, does this affect the matching of the relevant packets with the ACK-bit set? Additional question: If I want to match packets smaller than 128 bytes, would "match u16 0x0000 0xff80 at 2" do the thing?
