bimap problem

[Kaan G. Celik]

Hello,   I was trying to set up a network with both Port Address Translation and Network Address Translation on FreeBSD 5.1 with ipfilter & ipnat.   my /etc/ipf.rules are pass in all pass out all   Mainly I set up the BSD box, added IPFILTER support in the kernel and created /etc/ipf.rules and /etc/ipnat.conf   map fxp0 192.168.200.0/24 -> 209.x.x.2/32 proxy port ftp ftp/tcp map fxp0 192.168.200.0/24 -> 209.x.x.2/32 portmap tcp/udp 10000:65000 map fxp0 192.168.200.0/24 -> 209.x.x.2/32 rdr fxp0 209.x.x.2/32 port 5900 -> 192.168.200.254 port 5900 bimap fxp0 209.x.x.253/32 -> 192.168.200.253/32 My internal network is 192.168.200.0/24 on the xl0 interface   My external network is 209.x.x.0/24 on the fxp0 interface   Mapping all machines inside to outside IP works without any problem (209.x.x.2 is the fxp0 interface IP)   also the port redirection for vnc works well if I use the interface IP again   I have been trying different combinations for bimap for over 2 hours and still I am not successfull.   Nothing happens and when I try to ping 209.x.x.253 from another host in the external network, it simply does not get any response.   I have checked at least 20 different web sites/mailing list archives and the examples look the same.   I also thought about adding 209.x.x.253 to the fxp0 interface as an alias. But I am not sure if I have to, so I will do it after the comments.     Any suggestions will be greatly appreciated.   Best Regards, Kaan G. Celik [EMAIL PROTECTED]
