Hey guys, i’ve got a bit of a problem. heres the situation:
i had: router board (433 i think, with level 4 lic) with 1 x atheros ar5413 radio with 2.4ghz sector antenna, this distrubuted internet (dsl) from my local lan to a few of my freinds.
in the mean time i have had to cancel my dsl but still need internet. so i bought another atheros radio to install on the board in order to set up a link with my friend that has a 5ghz station & internet.
now i have the 5ghz radio set up & installed with a link with my friends station & i am able to browse his network, receive a DHCP ip & connect to the internet if i connect my laptop directly to the new 5ghz AP.
now for the big question:
how do i set the system so that my wired network & the guys connecting via PPPOE on the 2.4Ghz radio can also connect to the internet & see each other?
Well, if its a direct link to your friend and not via some WUG, then you don’t need like VPN like I have to do to use my friend’s ADSL.
I would ensure that your friend’s local (LAN) IP address range differs from yours, but the AP’s may be on the same subnet though. eg. his can be like 10.0.0.0/24 (10.0.0.) and yours can be 10.0.1.0/24 (10.0.1.)
When you have 2 different subnets, you can easily route the traffic from you to him and back, without having to enable NAT (masquerading) and having to port forward.
On your side you’ll have to set your default gateway to point to his AP’s IP address. It would be useful to also add a static route for his subnet to use his AP’s IP address.
On his side he’ll have to set his default gateway on his AP to point to his ADSL router’s IP address (if the ADSL is dialing the PPPoE connection).
Then he’ll also have to add a route for your subnet, using your router’s IP address.
