After looking into this further, I am still perplexed. Here is the
topology I started w/:
at work, i reconfigured my eth1 interface:
eth1 192.168.2.1 255.255.254.0
eth1:0 192.168.1.1 255.255.255.0
the windblows machine i have connected to eth1 is 192.168.1.100 255.
255.255.0 this configuration will conflict w/ the lan at home. when
i reconfigure the windblows machine to 192.168.2.100 255.255.254.
0, it arps but i cannot ping 192.168.2.1
i don't think the ip address is outside of the range of the netmask
but maybe i am incorrect?
my windows workstation
192.168.1.100/24 ------| debian gw corporate gw
|--192.168.1.1/24 -- 10.20.4.40/23
18.104.22.168/24 -----| my debian gw my home lan
|-- 192.168.1.1/24 ---|---192.168.1.0/24
So, to get any VPN working (openVPN in my case), I have to change the
addressing scheme on my windows workstation at work and the GW at work.
Easy enough, right? Well ... I thought I could change the addresses to
192.168.2.100/24 and 192.168.2.1/24 respectively. When I do this, the
workstation and GW at work do not communicate between each other. I can
see arp requests and replys between the two work 192.168.1.0/24
machines, but I cannot ping nor get to the corporate gw from the
workstation. I should know by now what I am doing wrong but it is not
obvious to me.
