[Scottish] ADSL router with no-nat configuration
Hi, I am having problems setting up a solwise SAR110 adsl router with a no-nat configuration and wonder if anyone here has set up an adsl router with a similar config. I simply want to connect the router to our smoothwall and have been allocated an address range of 4 ip addresses. The problem seems to be with the default route not going through the ppp interface. Our ISP said they cannot help, despite having tutorials for no-nat setups for two other types of modems but not this supplied one. I was able to set up the router with the standard nat option ok, but according to the ISP, to set it up as no-nat, all I need to do is configure eth-0 with appropriate ip address/mask from range supplied. To test this, I have set up a laptop with the other useable ip address/mask and the laptop and router can talk to one another. The router gets authenticated and connected to the ISP network (As confirmed by support) and sets up some dynamic routes. I have tried configuring the router by leaving the ip address of the ppp interface blank, which automatically gets allocated the correct ip address on connection and also set the ip address manually on the ppp interface. This is the routing table with a no-nat config where: address range: 212.159.29.4/30 dns: 212.159.11.150, 212.159.13.150 --- Destination netmask next hopifname type 0.0.0.0 0.0.0.0 195.166.128.11 eth-0 indirect 127.0.0.0 255.0.0.0 127.0.0.1lo-0direct 195.166.128.11 255.255.255.255 212.159.29.5 eth-0 indirect 212.159.11.150 255.255.255.255 195.166.128.11 eth-0 indirect 212.159.13.159 255.255.255.255 195.166.128.11 eth-0 indirect 212.159.29.4 255.255.255.252 212.159.29.5 eth-0 direct 212.159.29.5255.255.255.255127.0.0.1 lo-o direct the routing table with the nat config is similar but the default route is via ppp-0 0.0.0.0 0.0.0.0 195.166.128.11 ppp-0 indirect 195.166.128.11 255.255.255.255 212.159.29.5 ppp-0 direct The configuration (web and CLI) does not allow me to specify the interface when adding or modifying routes.

Re: [Scottish] FW: VPN
Hi Keith; I've never setup a VPN before but am I right in thinking that all that's needed is the right software and two static ip addresses With a 'nix box at each end that's about it. It gets a little more complicated if one of the gateways is MS or Cisco. Most Linux distros will include freeswan for IPsec VPN and there is PoPToP to use Linux as a MS VPN Server. -- ray ___ Scottish mailing list [EMAIL PROTECTED] http://mailman.lug.org.uk/mailman/listinfo/scottish

As has been noted previously, only one static ip address is necessary. Two is a bonus, as you can then restrict the vpn connections on a host by host basis, increasing security. I'm trying to help out a small community group set one up and they have received quotes for 11,000 upwards, although I never set a VPN up I always thought that it wasn't necessary to get special equipment. As is the way with a lot of things these days, you can often get both software and hardware based solutions for the same problems. Any advice on this would be much appreciated! If you have the luxury of two linux/solaris/bsd machines, one for each end of the link, then I can recommend vtun (http://vtun.sourceforge.net/), which I use daily. Depending on what you want to do, it can be a little fiddly to set up, but with a straight tcp based connection, it's pretty simple. -- Miah Gregory ___ Scottish mailing list [EMAIL PROTECTED] http://mailman.lug.org.uk/mailman/listinfo/scottish

It gets a little more complicated if one of the gateways is MS or Cisco. Most Linux distros will include freeswan for IPsec VPN and there is PoPToP to use Linux as a MS VPN Server. IPSEC can produce a number of additional complications - it was designed around an assumtion of connecting two (or more) points with fixed (real) IP addresses. Although a lot of these problems go away of you disable EPA (possible with FreeSwan - not with other implementations including MS) there are then implications for securing, configuring and authenticating the channel (e.g. opportunistic encryption is not available). Last time I checked, it wouldn't use x509 certificates either - although for a two site VPN this isn't so much of an issue. It does work and is reportedly very stable. Since IPSEC is a well established standard, it will interoperate with most other implementations (but not necessarily in all configurations). You pays your money and takes your choice.

Since the forums are not particularly active I'll try here. Can anyone planning to be at next Thursday's meeting help me out? I need a 60 metre cat5 cable, and retail prices scare me. I'm willing to pay any necessary costs (plus tip). If you can help, can you post an estimated cost? I seem to recall Micro Warehouse doing 300 metre boxes for about £40. Is that too scary?

Re: [Scottish] ADSL router with no-nat configuration
I called the suppliers/manufacturers of the router who told me that I need 3 useable IP addresses for this particular router to work in a no-nat configuration. So looks like I would never have got it working with the info the ISP gave me. Hopefully they will increate my address range.

If you just want alength of PVC solid core Cat5e/Cat6 with a booted RJ45 at each end it will cost you a pint of IPA. If you are not fussy about the exact length I have a few similar in stock. I can make a shielded cat5e patch cable (stranded core - more flexible and useful near flourescent light units and other noisy environments), but would have to make a modest charge as the cable is expensive and it is fiddly to put the connectors on by hand. If you need low halogen/ cable I would need a couple of days notice, because I don't have much in stock. If you are in a hurry 30m patch cables are pretty common and cost about £15 each (e.g. Tait Components).
