similar to: Do I need NAT?

I have need to use HTB on multiple (5) IPs. The present setup has the DSL connection going to a switch and then each computer with an external IP configures the external interface to listen on that IP. I have had TERRIBLE luck trying to use iptables to DNAT so if DNAT needs to be done, any advice that includes tested and working examples would be sincerely appreciated. There are 3 computers

Although this SmartLink comes with a Linux program to monitor it, I'd rather use nut if possible. The biggest reason for preferring nut is that the supplied software forces one to set the On Battery time rather than allowing the battery to go critical and then sending a shutdown. Guessing how long the battery will last is problematical, especially as the battery ages. The other big reason

Hello, Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts. First, what works. Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze. We have a 2 ISP: - isp1 : an optical fiber provider with 10 Mbps. - isp2 : a DSL provider with 15Mbits/1Mbits. We use isp2 as the default outgoing

Hi, At office, we have I ISPs. I want to lightly monitor each link latency in order to decide several routing. For that, I have only one external server: 1 IP, it's an OVH dedicated server. The quick picture is http://s24.postimg.org/n3436z64l/defaul_route.png Default route is via ISP1. If OVH-server pings IP1: - the request will go through ISP1: it's OK - the reply will go through

I''ve just started to recently look at CBQ and HTB, but I''ve been wondering whether or not something like the following is possible: I''ve got two external links: +--+ | |-----ISP1 |FW| | |-----ISP2 +--+ One link has a bandwidth cap, and the other doesn''t.

Hi there. Currently, our network design has two ISP lines and 3 subnets for LAN. Below are some details :- eth0 - isp1 eth1 - isp2 eth2 - subnet1 eth3 - subnet2 eth4 - subnet3 What i wanted to do is to assign incoming port 80 to our local squid server running on the firewall itself and assigned it to eth0(ISP1). I think it shouldnt be a problem as /etc/shorewall/rules provides a sample of the

hello, i have 2 links to the ISP of 128kbit each, and i want to balance the trafic between them, but not staticly (local ip1-5 throw isp1, and the rest to isp2). I though at a ingress clasification, then routing by the mark, and at the exit nat (yes i must do nat :(((, but the clasification must be flow based, and i dont know how to do it.

Dear list, Shorewall is running here with 2 ISP''s: ISP1: corporate ADSL-line with fixed set of IP''s ISP2: fast consumer-grade cable-connection with higher bandwidth All our main traffic (web, e-mail) is routed trough ISP1. Only for special purposes (frequent large ftp-transfers) ISP2 is used, configured trough tcrules. ISP2 is not so reliable as ISP1 (duh) and they sometimes

Here''s my situation: I''ve got an Intel machine running a 2.6.9 linux kernel and this box has 4 modems attached to it via a usb to serial port expander. In order to force data down each of the modems, some pretty simple rules are used and they are as follows: iptables -t mangle -A OUTPUT -p tcp --dport $PORT1 -j MARK --set-mark 1 iptables -t mangle -A OUTPUT -p tcp --dport
