First of all,sorry about my bad english,when we talk about linux problems it's a kind a hard to me to explain,becose,this is an english that i didn't learn at school. My server it's an Redhat 6.0 compatible (portuguese ver name Conectiva4.0,kernel 2.2.12-5)with 2 interfaces eth0 and eth1. eth0 IP = 192.168.0.3 Intelpro 100 eth1 IP = 192.168.1.3 VIA86c100A I'm not using a modem to connect to Internet,i have an ISDN TA/ROUTER name YAMAHA it's an 10M router.And i'm connecting to this router via LAN instead COM port,and the IP of this device is 192.168.0.1 .So,all the configurations of my ISP go inside this router,ISP phone number,DNS primary and secundary of the ISP etc.And with a browser i can ask to the router to make the connection with my ISP. The problem,i can't reach the internet using 2 interfaces: Before i get into this trouble,i was using just one interface eth0,and all clients and linux was accessing the internet just fine.But,i never got my ipchains to work with that configuration,and to try to make ipchains and MASQ to work,i installed a second LAN card to work as eth1.So my intention was,separate things,to MASQ my internal IPs to external.But it's not working at all. I also have a "fake,not valid outside my intranet" DNS that was running on my eth0 device,now with 2 interfaces i dont know what to do! My DNS dont work anymore,my machines can't reach the internet.If i shutdown one interface eth0 or eth1 the dns and internet start to work again?? My interfaces are up and running,with ifconfig i got no errors on the devices. lsmod does't show nothing wrong: [root@server /root]# lsmod Module Size Used by via-rhine 8840 1 (autoclean) eepro100 12112 1 (autoclean) Any one got an ideia of what is going on here???I read the HOWTOs,docs and can't find a anser to this problem. How can i work this out? How can i sign the IP from my ISP to the internal machines? The organization of my little intranet looks like this: The router is connected directly on Linux interface eth1. The interface eth0 it's connected directly on my HUB (8 channels 10/100 auto switch). All my clients(5 in total,3 G4s and 2 WIN98)it's connected to this HUB too.The gateway of the clients are set to look on 192.168.0.3(eth0). The ipv4 routing it's running and this it's my /etc/sysconfig/network: NETWORKING=yes FORWARD_IPV4=yes HOSTNAME=server.wtulinux.co.jp DOMAINNAME=wtulinux.co.jp GATEWAY=192.168.0.1 GATEWAYDEV=eth1 Thanks in advance for any help! ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
