Cannot ssh through my dhcp server

tallmtt · 10-21-2008, 09:39 PM

My home network consists of, among other things, a dhcp server, a wireless laptop (connected via interface br), and a hardwired computer (connected via interface eth1).

I can ssh from either client (laptop or computer) to the dhcp server, but cannot ssh from one client to the other.

Someone on an IRC channel asked me about this:

Code:

myusername@myhostname:~$ sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

I am not running an NAT server (and I would like to be able to ssh between all clients - not just these two)

The firewall configuration is performed with shorewall.

Thanks for any and all help!

can you explain your topology more accurately? you are bridging two interfaces on the box? in that case this is not reouting / forwarding so the iptables stuff is irrelevant. I wouldn't recommend bridging, it's often simple but unusual. let switches switch traffic, not servers. have a seperate wireless and wired subnet and then do route to them. i don't believe shorewall deals with securing bridged networked (which is done via ebtables instead of iptables).
