Luke, Thank you very much, your advices were very helpful and I now have a working port forwarding through two routers. Sorry for the delay in the answering, it took me some time to test various options... Actually your (A) advice is what did the job. I turned off DHCP server on ADSL router and enabled NAT - DMZ Host option on it (for which I realized that it was the closest to your description of bridged mode). Then I configured the wireless router to use static IP config instead of expecting DHCP server. The situation is now this: INTERNET | telephone/adsl-wire | | ADSL router wan : xx.xx.xx.xx FreeBSD box (wired) lan : 192.168.1.1 ip: 192.168.0.102 | laptopgateway: 192.168.0.1 | (wireless)| [internet plug]ip: 192.168.0.101 | Wireless router gateway: 192.168.0.1 | wan : 192.168.1.2:| lan : 192.168.0.1 . . . . . :| [ethernet plug] | | | +---+ DMZ host for ADSL router is 192.168.1.2 -- and it works! I have one question more (forgive my ignorance): now the wireless router is configured to use static IP config and I must provide one or more Static DNS servers to it. Is it ok to type just 192.168.1.1 as DNS (which works for now) or to copy DNS servers which are automatically provided to the ADSL router by the ISP? Your solution is a little different from what I was suggesting, but it might be a better solution in some ways. If 192.168.1.1 really works as a source of DNS, I would take that to mean that your ADSL router is passing your name requests along to the nameservers that the ISP provided it. That's good. If your ISP ever moves its nameservers, it will tell your ADSL box about it, and the changes should propogate. If you hardcoded your DNS addresses into your wireless router, you would have to change them by hand if a change was ever required. I believe your wireless router is now responsible for being the firewall for your network, so make sure you've set that up. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Port forwarding behind two routers
Good day people, I'm trying to get wireless Internet access for my laptop and to use this wireless router as a switch for my FreeBSD box at the same time. This wireless router has one Internet plug and for Ethernet plugs for wired boxes. Now I have this situation: INTERNET | telephone/adsl-wire | | ADSL router wan : xx.xx.xx.xx FreeBSD box (wired) lan : 192.168.1.1 ip: 192.168.0.102 | laptopgateway: 192.168.0.1 | (wireless)| [internet plug]ip: 192.168.0.101 | Wireless router gateway: 192.168.0.1 | lan : 192.168.0.1 . . . . . :| [ethernet plug] | | | +---+ The wireless router software configured the router like this: Destination LAN IP Subnet Mask GatewayInterface 0.0.0.0 0.0.0.0 192.168.1.1 WAN (Internet) 192.168.0.0 255.255.255.0 192.168.0.1 LAN Wireless 192.168.1.0 255.255.255.0 192.168.1.2 WAN (Internet) ... so it works as a switch for two boxes and as a router at the same time. The FreeBSD box is configured like this: ifconfig_XXX0=inet 192.168.0.102 netmask 255.255.255.0 defaultrouter=192.168.0.1 Now I have Internet connection on both computers. However, I can't get aMule and other apps that need port forwarding working on FreeBSD box. First, I tried to configure ADSL router (192.168.1.1) just to forward 4662 port to 192.168.0.102, doesn't work. Then, I tried this: 192.168.1.1 router: forward 4662 to 192.168.0.1 192.168.0.1 router: forward 4662 to 192.168.0.102 not working again. I have a feeling that I'm missing something very simple, but can't figure out what. (A note: before I acquired a wireless router, forwarding with one router was just working, with FreeBSD box configured as 192.168.1.101, so that side of things is ok. And, no, it's not possible to use just wireless router because I can't plug telephone wire in it.) Can anyone help me? Should I post more details?
