Jeff, Since you are using bridge mode, try adjusting down the MTU supported through the network. We have observed that a realistic MTU for Verizon 5G home internet is about 1428 bytes. Good luck, Tom On Sun, Mar 19, 2023 at 8:00 AM <nanog-request(a)nanog.org> wrote: > Send NANOG mailing list submissions to > nanog(a)nanog.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.nanog.org/mailman/listinfo/nanog > or, via email, send a message with subject or body 'help' to > nanog-request(a)nanog.org > > You can reach the person managing the list at > nanog-owner(a)nanog.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of NANOG digest..." > > > Today's Topics: > > 1.

Re: Spamhaus flags any IP announced by our ASN as a criminal network
by George Toma 21 Mar '23

21 Mar '23

I do not believe ASN sharing is illegal or prohibited, it's not prohibited in LACNIC and in APNIC policy I also could not find anything about ASN sharing, only APNIC policy states: "2.3. Autonomous System (AS) An Autonomous System (AS) is a connected group of one or more IP prefixes run by one or more network operators under a single and clearly defined routing policy. 2.3.1. Autonomous System Number (ASN) An Autonomous System Number (ASN) is a unique two- or four-byte number associated with an AS. The ASN is used as an identifier to allow the AS to exchange dynamic routing information with other Autonomous Systems." Nothing prohibiting ASN sharing and 2.3 specifically states "run by one or more network operators... single routing policy" Regards George On Tue, Mar 21, 2023 at 8:00 AM <nanog-request(a)nanog.org> wrote: > Message: 19 > Date: Mon, 20 Mar 2023 16:24:09 -0400 > From: ayang(a)august.tw > To: Collider <large.hadron.collider(a)gmx.com> > Cc: nanog(a)nanog.org > Subject: Re: Spamhaus flags any IP announced by our ASN as a criminal > network > Message-ID: <5b7ed1b1fbff65dfc63d188c2e1f95af(a)august.tw> > Content-Type: text/plain; charset=UTF-8; format=flowed > > Several Huize ASNs, e.g. AS47158 and AS141011, were revoked due to RIR > policy violations, which include prohibited sharing of ASNs with third > parties, IP hijacking, and malicious path prepending. > > Given this history, it is not surprising that Spamhaus would blacklist > IP addresses associated with their ASN.

Anyone from Google Global Cache ?
by George Toma 21 Mar '23

21 Mar '23

Hello, Is there someone on this list from the Google Global Cache program (GGC) who could contact me off-list? If so I would greatly appreciate that. I would need a favor to get some information and look up a case because the responses to the tickets in the ISP portal I am getting are not giving me any meaningful answers. Thank you Regards George Toma

Looking for someone at ipligence and/or Washington Gas
by Glenn McGurrin 21 Mar '23

21 Mar '23

I'm recently become a customer of Washington Gas but their website won't let me see anything claiming I'm in the Netherlands and so they are blocking me. I'm not sure how the geolocation data got screwed up, as far as I can tell this IP block has never been there and every geolocation provider except for ipligence shows it in pretty much the right spot near Washington DC. Phone call to Washington Gas says email their support, their support has an auto reply saying they will get back to me but never does, I've just send the 3rd email there, the first two being the 17th and 23rd of February, so the 24-48 hours their autoresponder claims is clearly a joke. I've also submitted a contact to ipligence as they seem to be the geolocation provider in use as they are the only one with the bad geolocation data and it matches what Washington Gas claims, but no response there either and their site still shows the bad data more than a month later. I've added the one person I could find at Washington Gas via searching around to the second and third requests but it seems no one is even looking at their email and they will not help via the phone saying it's a different department and to email, at this point I'm not sure what to do other than reach out here to hopefully find someone with a clue, try publicly calling out on twitter, and possibly file a complaint with the regulators as that seems the only way they might bother to even reply. If anyone at either company is here please contact me or if anyone has a contact at either company I can try please let me know. Thanks, Glenn

Cisco is sending the in and out packets in their sFlow implementation on their Nexus switches. Obviously, this double counts the information. Are there solutions that process those flows and remove one of those directions? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Verizon/Qwest single end-user difficulty vs Xfinity
by Jeff Woolsey 19 Mar '23

19 Mar '23

Verizon 5G Internet Support is not at a high-enough pay grade to assess this problem... So I'm turning to y'all. I'm trying to save $$$ and increase speed, using Verizon 5G Home Internet to replace XFinity, even though they gave me a faster modem a few weeks ago. I run both of the modems in Bridge/Passthrough mode. A friend of mine is nice enough to offer some offsite backup space, and I use rsync over ssh to get there. He's 1500 miles away. He uses a non-standard ssh port (keeps the doorknob twisters away). This sort of thing has been working without difficulty over Xfinity (my end) for years. He also changed his connection almost a month ago now, to Qwest, I believe. I try the same thing over Verizon [1] and ssh always times out, no response. We are also NTP peers, and that doesn't work well over Verizon either. ICMP traceroutes and pings succeed. UDP traceroutes do not get any further than 207.109.3.78 (last hop before destination) . Not every traceroute offers TCP, but MacOS does, and nothing responds to any of that, even at the usual ssh port. UDP traceroutes to either port behave like an ordinary one, which it is. Since I can get there via xfinity, I can traceroute, ping, but not ssh back through Verizon. I also set up an incoming (xfinity) port from the same non-standard ssh port forwarding to regular ssh on a different system on my LAN, and when I ssh -p <port> that from Verizon (even cellphone data), I get that other system, and that works fine. The 207... router is not in that path. I can also ping the Verizon connection from Xfinity (and vice versa). Go figure. [1] This same difficulty occurs in Verizon's Looking Glass, from several different places, and other Looking Glasses (e.g. Cogent, Equinix). It also occurs on my Verizon phone data connection (not WiFi). If he were serving more stuff out of his home, this would be a bigger problem. -- Jeff Woolsey {woolsey,jlw}(a){jlw,jxh}.com first.last(a){gmail,jlw}.com Spum bad keming.
