Help to prevent a divorce!!! (Internet access /NAT etc)
Oh boy am I getting some stick - not altogether unjustified either!
Ok, the setup WAS as follows:-
Broadband connection to a wireless router / 100Mb Switch.
2 Laptops connecting over wireless directly to the internet (router performing NAT)
1 Linux server (LFS 6.0) running SQUID, SAMBA, Dan's Guardian, Postfix, ClamAV and HavP. Also providing DHCP and DNS services.
2 Desktop PCs connecting over wireless to SQUID. (The kids).
All this worked fine - then we moved house.
We now have cable, so we can no longer use the wireless router for broadband access. I have connected the Linux box to the cable modem and it seems to be working OK. Also, if I connect the laptop directly to the cable modem (as I have to post this), it works fine - so I assume the internet link itself is fine.
Now for the problem.....
I need to get the Linux box working as a busybox. I can connect to the internet via SQUID etc OK, BUT I am having problems with a lot of the sites we adults use - mainly those involving https (internet banking, e-bay etc). It is either extremely slow (to the point connections time out) or gets blocked. This slowness also seems to depend on the site accessed (although not neccessarily the protocol used).
I would like to get the linux box running NAT so the laptops can connect directly, but when I try following the how-to's I can find, not only doesn't it work, but access to SAMBA, DHCP, etc etc is blocked.
I have set up packet filtering and stuff on other systems (most noteably NetWare running BorderManager) but that was some time ago and I can't get my head around IPTABLES at all.
Let me know if any other details are required.....
I wasn't sure if this should be posted in the networking forum, apologies if I misjudged - let me know and I'll repost there (I didn't want to cross-post!!)
Thanks in advance for any help.
