search for: adsl1

Hi folks, I know this isn''t a shorewall question, but i''m hoping someone can point me to the right place to look for answers on this (since, as Tom suggests, search engines are useless for some things): Here is my firewall setup: ADSL1 ADSL2 dialup \ | / firewall | DMZ It''s a fairly simple setup. ADSL1 has a static IP, ADSL2 is dynamic. There is DNAT across both ADSL links to a single host in the DMZ. The dialup IPs (a /29 subnet) are routed into the DMZ. ADSL1 is my normal default...

I made a script to test if in a moultiple gateway setup all default connection are up, regardless of the fact that that gateway is the default gw. Suppose adsl1 and adsl2 are present, and all traffic goes by default to adsl1, and you want to test if adsl2 is ok. 1. I use mangles from iptables to mark icmp packets to some test machines 2. I set up a routing table for each adsl 3. I use ''ip rule'' to route marked packets to the gw...

I'm using shorewall 3.0.4 with ubuntu dapper. I've compiled the kernel with the option CONFIG_IP_ROUTE_MULTIPATH_CACHED=n. I had a trouble with, pptp connection, I'm trying to connect a using microsoft vpn a vpn server out of my lan, and don't work. My files <providers> ADSL1 1 1 main eth1.600 10.190.1.1 track,balance eth0 ADSL1 2 2 main eth1.601 10.190.2.1 track,balance eth0 </providers> <tunnels> pptclient net 0.0.0.0/0 </tunnels> And I tried with tcrules <tcrules> 2:P 10.100.0.0/24 0.0.0.0/0 tcp 1723 </trcules> What's wrong ?...

...LARTC recommends. I am able to direct traffic for specific internal IPs either to one or the other ADSL line. However, I am faced with two problems I am struggling for the solution: 1. I have opened a few ports on the ADSL router/firewalls to talk to internal hosts; say when someone hits http://myADSL1_IP I would redirect him to 192.168.0.10; while if someone hits http://myADSL2_IP I would redirect him to 192.168.0.20. If I have rules such as the following all works well: ip rule add from 192.168.0.10 table ADSL1_rules ip rule add from 192.168.0.20 table ADSL2_rules Unfortunately, if I want...
