Kim, : I'm having a problem with multiple internet providers. According to all : the things I have found so far it should not be that uncomplicated to : set it up - however, I'm having some problems getting it to work. You are correct. It is not uncomplicated. It is also not difficult. :) : Firsth the scenario - I'm having 2 Internet providers, one fast with 32 : static IP's and one slow with dynamic IP's. Internally we are using a : private net which is set up for 32 ip's. Now, we have to map all 32 : static ip's to the private IP's so all machines can be reached : externally through the static net. The default route is suppose to be : the slow ISP. : : So far, I have found that I need to set up the routing using marking, : and then set up the rules so it work accordingly. That's one approach, documented here: http://linux-ip.net/html/adv-multi-internet.html This only works if you are not trying to perform link load balancing. If that is your intended goal, you'll need to check out the Nano-HOWTO (Hey Julian--this appears to be missing right now): http://www.linuxvirtualserver.org/~julian/nano.txt : But this appears to just work with static routing, not when one of the : providers is dynamic! It doesn't matter that the IPs are dynamic, just that you can alter the affected routing table when you get a new dynamic IP. If you are using rp-pppoe, you'll want to perform your additional routing table manipulations in ip-up.local. And also, unless you have a routing daemon, you are using static routing. A dynamic IP address is simply that--your network-connected machine is still performing static routing, though it has a dynamic address. Since you have a dynamic IP on one interface, you may wish to use the -j MASQUERADE target instead of the -j SNAT target. : Does anyone have some suggestions for what to do? Do the above suggestions help? -Martin -- Martin A. Brown --- SecurePipe, Inc. --- mabrown@xxxxxxxxxxxxxx
