1. IPTABLES BPF not work Backgroud : u32 module is not working, try to use BPF instead. some packages must be detected by byte@offset. Since NFBPF_COMPILE is not available in either tomato and recent x86 linux, the bytecode is actually generated by I'd like to know which step is wrong. 2. install binaries Later I found it is too bothersome to download tcpdump all the time, and tried to copy that to "/usr/sbin/" Actually the tor bounded with FreshTomato is not a complete package. We need obfsproxy to make connection with some bridges. Anyway, i cannot copy any executables over here. Some suggestions please.
