Hi, Suse 9.1. I'm trying to redirect all request to port 5905 to IP:192.168.0.10:5901. Did this: FW_FORWARD_MASQ="0.0.0.0/0,192.168.0.10,tcp,5905,5901" The forward works well but I receive always this error in the log files: Oct 19 08:52:04 linux kernel: SFW2-OUTPUT-ERROR IN= OUT=eth0 SRC=192.168.0.30 DST=192.168.0.11 LEN=68 TOS=0x00 PREC=0xC0 TTL=64 ID=50253 PROTO=ICMP TYPE=5 CODE=1 GATEWAY=192.168.0.10 [SRC=192.168.0.11 DST=192.168.0.10 LEN=40 TOS=0x00 PREC=0x00 TTL=127 ID=39644 DF PROTO=TCP SPT=4426 DPT=5901 WINDOW=65535 RES=0x00 ACK URGP=0 ] Why??? Regards, Andy.
