I'm one of the non-business customers with routing problems since I got shifted to their /29. As I wrote last week:
"The problem is that the start IP address of my block is also the WAN IP of the ISP (Timico). They used to be separate addresses, quite distant from each other. This doesn't play ball with my Belkin modem, and as such it's mucked up my network until I can spend time diagnosing."
I have two ADSL2+ modems, one Belkin, the other Linksys, and both are having trouble routing with Timico. I've had various different /29 over the past 10 years my exchange has had ADSL, and each time there's been no problem preforming the changeover on my network. Until Timico took over Coms and gave me a new /29. Each time I had a change of /29, all I'd do is change one entry in my modem's config file -- changing it to the new IP for ex 220.127.116.11 (where my new block is 18.104.22.168-8) from 22.214.171.124. The WAN IP that my modem displays -- and is what the ISP gives me when I authenticate on their network -- is quite far from the /29 block that they allocate me. Timico are different. The WAN IP they give me when I authenticate is the start IP of my /29. This is what's causing problems.
Strangely, if I configure the modem to, say, 126.96.36.199, and my iMac to 188.8.131.52, I can use the iMac to connect to the internet, but the modem is invisible from my side of the network. I can only configure it externally via tethering something to my Three mobile phone. Additionally, nothing else on my network can see the modem on 184.108.40.206 thus my wireless router (which is a separate device to my modem) can't see it, thus I have no home wifi. I've been relying on using Three's mobile data since a week, so I dread what my bill is going to be like.
This could be resolved if Timico allocated me a WAN IP on authentication that was distinct from the /29 they allocated me. I have tried taking this up with Timico support, but they don't understand the problem.
