Iliad 5GBITs

yellowdaisydoo

Hi guys, I see Iliad are doing 5gb fibra. I wondered if anyone out there is using it and how is it going?
I see from the info that the router uses three ethernet ports (2,5gb,1gb,1gb) and wifi at 0,5gb to get to 5gb which seems a bit strange. I'm on Vodafone at the moment which is 2.5gb but if I0m not mistaken the ethernet port isn't 2.5gb but only 1gb so even if the Iliad does this strange thing at least one port is 2,5gb. Or am I reading things the wrong way?
Does the router join these three ethernet ports into one or are these three separate internal networks?
Does the router have a VPN client and if so is it possible to decide which devices use the VPN ?
Thanks!

It's correct.

yellowdaisydoo Does the router join these three ethernet ports into one or are these three separate internal networks?

It's only one network but you need 3 devices (unless you go the route of load balancing or other nasty stuff)

yellowdaisydoo Does the router have a VPN client and if so is it possible to decide which devices use the VPN ?

If I recall correctly (it was not discussed much here) it only does VPN Server.

No it's correct that way. The iliadbox has three ethernet ports: 1x2.5Gbit, 2x1Gbit. Those combined with the wifi can get your total network usage to 5 Gigabit, but with this router you cannot get 5Gbit on a single device, the maximum you can get on a single device is 2.5Gbit.
You can set the iliadbox in "ONT-Mode" but you will be limited to the 2.5Gigabit port. Or I guess you can buy some very expensive equipment to replace it and use 5Gigabit on a single device.

It's right, with Iliad you get the announced 5gbit by the aggregation of the 3 eth ports (2.5 + 1 +1 + wifi)
Yes, still by Vodafone either the 2,5gpon connection is limited by the 1gbit eth ports of the router.
Yes you can get a VPN connection with Wireguard by design on the Iliadbox.
Mind that the Epon Iliad MAP-E infrastructure gives you a 1/4 ports dedicated IP. 1 to 16k and so on, so in case you used to publish services on strategic ports, keep in mind you could change the way you do it. The assignment of the ports sector is totally random.

Crossway quali sono apparecchiature molto costose per avere i 5Gbps su un unico PC?

Crossway Or I guess

They exist, but there are only a few of them on the market, and nobody tested them with Iliad, so I've got no guarantee they will work. This is one example.

thanks for the replies guys, sounds good. I looked in the forum to see if anyone is actually using it and if they have had problems but I couldn't find much.

To be fair there are quite a few, mainly two:

In some areas it could suffer from micro service disruptions that keeps you out of internet for ~ 15-60 seconds . It could be a problem during meetings and video calls, you shouldn’t notice it in streaming and browsing.

Upstreams and peers,”the pipe” towards big internet, are not the best, compared to other major ISPs.

yellowdaisydoo Are you able to tell which part of Italy (city preferred) would you subscribe the connection?

yellowdaisydoo

Genova!

Daniel_e88

yellowdaisydoo So my city, i can grant you that Iliad is working best. I do have Iliad too from day one and except some random disconnections few months ago, the line is working fine.

yellowdaisydoo

Do you think I could use my Asus AX-11000 instead of the Iliad router?

edofullo

yellowdaisydoo There is no (decent) way to replace the Iliad router as of right now.

You can put that router in series to the Iliad one in 'ONT mode' if it can SNAT to a specific port range (I doubt it) or somehow manage to get a public IPv4 from Iliad.

Or just cascade it with double nat.

edofullo SNAT to a specific port range

Well, OpenWrt (and Linux in general) can do it, and it's pretty easy with Iliad since there's only one single contiguous port range, so you'd just need to put the port range after the IP address, like this:

iptables -t nat -A POSTROUTING -o ethXX -j SNAT --to-source 192.0.2.123:16384-32767 (example)

(In OpenWrt you'd add it in /etc/firewall.user, in the postrouting_wan_rule chain instead of POSTROUTING, where wan is the name of the interface in /etc/config/network.)

You could even do it with -j MASQUERADE --to-ports 16384-32767 but I can't really see the point in doing that (static ports but "dynamic" IP?! 🤣)

Instead with Sky there would be lots and lots of smaller ranges, so it'd be a PITA to configure it with so many iptables rules and statistic matches (and it still wouldn't be "perfectly" balanced...), since unfortunately, multiple port ranges in a single SNAT rule aren't supported by Linux.

edofullo manage to get a public IPv4 from Iliad

It seems they don't give "full stack IPs" out anymore with the "normal" iliadbox plan...

Heh, if only the "net neutrality" plan was actually usable... 😢

edofullo

LATIITAY He mentioned an Asus device, I don't think it supports SNAT to a custom range out of the box, he likely need a custom firmware (Merlin) at the very best.

Hi! I just recently got Iliad 2.5Gbit and I'm currently running a double NAT (with DMZ to the cascading router) because I'm still trying to make the ONT mode work correctly. When I activate it I can ping any IP, but no online application works and pinging URLs doesn't resolve IPs. This is expected given what you wrote above @edofullo and @LATIITAY .

LATIITAY iptables -t nat -A POSTROUTING -o ethXX -j SNAT --to-source 192.0.2.123:16384-32767 (example)

The router under the Iliadbox is running OpenWrt 22, and unfortunately they removed iptables in favor of nftables. I'm not familiar enough with them to translate the above command to setup SNAT. Would you be able/willing to help with this?

I can see the range of IPs I got assigned from the Iliadbox admin page, but what does the IP at the end of the example represent?
192.0.2.123
Would that be the OpenWrt router itself or something else?
