Hi all! I''ve got 2 (soon 3) internet connection. 1 - via ADSL, 2(and3) via ppp My network: http://desima.objectis.net/network-diag linux1: user1.user2 eth0=192.168.1.1 ppp0=192.168.5.2( gw 192.168.5.1) gw=192.168.1.2 ( thru ADSL) compA=192.168.1.6 compB=192.168.1.15 gw2=192.168.1.217 via ppp to different ISP All works for compA and CompB, user1 should use default gw(192.168.1.2)

Hi, I would like to set up access to Internet via two providers. When they both works OK I use ip route add default scope global nexthop via x.x.x.x dev eth0 weight 1 nexthop via y.y.y.y.y dev eth1 weight 1 Next, I use script that regularly pings their upper providers for see if some of providers are down. If one is down I want to guide all communications via other interface. If second one

Hello, I''m trying to set up a gateway for a local network to use two dsl lines. Ok, I read the LARTC howto and set up two routing tables and the correct balancing default gw. It works fine for connections originating locally on the gw machine. Then I added two iptables rules on the nat table: iptables -t nat -A POSTROUTING -s 192.168.4.0/24 -o $TI_IF -j SNAT --to-source $TI_IP iptables

Hello all. First of all, please be a bit indulgent to my poor English :-). Second, this message is "kinda" BIG, so if you don''t like BIG messages, simply don''t read it :-). I''ve read http://shorewall.net/2.0/Shorewall_and_Routing.html and http://shorewall.net/MultiISP.html, however I still a bit confused how to organize what I need :-). I''ve a

Hello! I have the following setup: 1) a connection to my ISP with a public IP (1.2.3.4) with the gateway 1.2.3.1 2) an allocated IP class with 64 addresses (5.6.7.192/26) 3) two LANs connected through two NICs: a) 192.168.0.0/24 on eth1 (192.168.0.1) b) 10.0.0.0/24 on eth2 (10.0.0.1) The IPs from the allocated class are all assigned to eth0. The networks are SNATed to the external IP and

Why ping google ??? you should either ping your assigned external ip address ( make your config dhcp for your external ip address even if it is static ) ( If your dsl link is up you sould have an address if not you should not ) If for some reson you cannot do that, ping your isp''s default gw or someone closer. With google you never know what is going on. I do something similar with -m

Hi! Me and two friends are trying to get a VPN working, but we cant get routing between two tunnels. This is how it looks, all servers (192.168.*.1) are running IP Masquerade to enable the other computers behind them to access the internet. Both elayne and glenn are connecting to melc, and the tunnel between melc and glenn are running TCPOnly because that glenn doesnt have a public IP (it's

Ok folks, here goes.. I have been boggling with a problem for the past week, and still haven''t found a solution.. I''m trying to route traffic from two providers through a Linux machine. But that is not the problem. The ISP''s have provided me with a WAN IP class for both of the lines, to be routed into a DMZ where the machines a to respond to their respective

Hi all, I am using a redhat 8.x linux box configured with zebra routing software which is also configured with ospfd I have 2 backbone routers running ospf connected to different isp''s I have 3 local routers also running ospf within themselfs and also with the 2 backbone routers (all are linux boxes) router A - backbone router 1 router B - backbone router 2 router C - local router 1

Hi list, I''m trying to setup a Linux box with a complicated source routing and could use a hand from you. The box has 4 NICs and lots of VLANs attached. It is a firewall and router in the following scenario: (obs: IP addresses have being changed for security purposes) - eth0 holds the default route (GW: 200.1.0.1, Firewall: 200.1.0.2); - The box is routing and sometimes source

Hi! sorry my english (soy de Argentina) This is my scene: ISP 1: IP X.X.X.7/28, GW X.X.X.1 ISP 2: IP X.X.X.22/30, GW X.X.X.21 LINUX SERVER: eth0, ISP 1 (default) eth1, to intranet 192.168.1.0/24, 192.168.6.0/24, 192.168.50.0/24 (aliasing) eth2, to intranet 192.168.8.0/24, 192.168.9.0/24 eth3, to intranet 192.168.0.0/24 eth4, ISP 2 eth5, to intranet 192.168.11.0/24, 192.168.12.0/24 I need two

hi everybody I'm having a, I'd like to think a "regular" VPN with IPsec/xl2tpd and it all works OK, except.. One thing that I never needed but now I do and I wonder.... is it my iptables, or/and routing or maybe VPN server config..? vpn clients with established tunnels can get to VPN server's NICs/IPs but cannot get through to the net behind the server. Well... they can,

Hi all Could someone please me with my current setup. I just got another DSL line and I have my routing and marking the packets etc so that I can decided the fate as to which ISP I would like to route my traffic out of etc. I managed to get squid to be used as a trasparent proxy, but im forced to use the default gw of the machine and for the likes of my I cant figure out to send traffic out

First of all, I''d like to thank Andy Furniss for his direction and for helping me get a working example up and running. For the following set up to work, you will need a linux computer at the ISP (server), a linux computer at the client location (client), and some a public range of IP''s you plan to send down to your client. (as this configuration involves patching the linux

A site I administer has dual T1''s. We have this set up according to NANO-HOWTO[1] using Julian''s routes patch on a late model 2.4 kernel. All is well, has been working well for a long time. Recently one of our T1 providers went belly up and we got something better. Now we have a /28 where previously we only used one IP per interface. Present interfaces: eth0 - T1#1, single
