ip route config question, forcing src address
I''m trying to use ip route to setup a single interface with two ip
addresses. I currently have:

Howto? 2 interfaces, same network, same gateway
Hello
Summary:
I have ifplugd managing eth0 and wlan0 (both dhcp). When I plug in the cat5
(which brings up eth0) applications which have already bound to wlan0 stop
working, obviously because wlan0 for some reason is unable to get non-local
packets out that interface.
I figured if poodoze is able to have both interfaces working, then linux must
surely be able to do it as well.

SFTP
(anonymous post) I have a simple 2 interface firewall setup and all is
good, almost. I am hosting virtual websites and DNS behind shorewall no
problem. However I am trying to use SFTP via a different port number and
have no luck even though Putty works well. Is there anything weird to
sftp and shorewall? My lab uses a different firewall (firestarter) and
it works OK.
I am using;

2-3 uplinks, nat and failover...is it possible?
Hello,
I am trying something crazy here. I have gone through the old
archives, lartc.org and lot''s of documentation, but still something is
wrong.
Here is the situation;
The server is Fedora core 2 running kernel 2.6.5
I have 2 uplinks to two different ISP''s. (It will be 3-4 in the future).
These ISP''s should serve the bandwith to local clients with multiple subnets.

After upgrade people can no longer connect
Hello Tom,
I''ve been using Shorewall for years without problems. My previous version of
shorewall was 1.4.6b-1. Everything worked just fine. Today I upgraded using
rpm to 2.0.8-1. After update no one can connect to any interface from net.
Server can connect to outside world fine and those described in routestopped
have no problem connecting. Any help correcting this problem would be

ip aliasing and loadbalancing with iproute2
Hi,
We have two internet connections and I would like to loadbalance between the
two using advanced routing. The gateway machine to my lan has two
interfaces, one connected to lan(eth0) and other to wan (eth1). The wan
side interface is connected to a switch which is terminated with two
internet connections from two ISPs.
I have added the routes as follows,

Policy routing question
Hi,
I have a testing multihome setup, with the default gateway being one of
the links and using policy routing to honor requests for a specific
link. Everything works as expected when I request a specific IP to bind
to. But if I request a specific interface things fall apart in ways that
I can not explain:

Wireless connectivity issues
Hello,
I cannot establish Xserver connection via wireless subnet, while telnet is
working fine. There was a similar problem before in Shorewall over IPSEC
that Tom had fixed. Also, ping is working, but traceroute is not. Finally,
PuTTY gets a connectivity error after couple minutes of inactivity over
wireless when connected to the firewall/gateway.

Question about limited primary addresses
I just realized that I hadn''t actually asked a question when I posted
this before. Let me try again...
I am trying to configure a Linux box with all possible VLANs (4094 of
them), and a subnet on each VLAN. Creating the VLANs isn''t a problem.
But, when I try to use "ip addr add ..." commands to assign an IP
address to each VLAN interface, I get to do about 280 of

As I boot my computer ( single workstation ) I do not get any connection
