Check if the third-party router remains useful despite the bridge mode issue.
Since no details were provided about the new ISP or router, it's hard to determine what would make a difference.
It relies on the router's performance. I received a Sky-provided router, but the WiFi signal was extremely weak. I connected my Nighthawk R8000 to the Sky Hub, and everything functioned perfectly.
Master Disaster is testing their fritzbox home server router to secure the best deal, and it appears to be a significant setup.
Using my ISP ATT, their Residential Gateway lacks bridge mode support. Even though they offer a configuration to forward the public IP to a downstream router, you remain connected through the RG NAT/FW session table. Issues like 6in4 tunnels (IP proto 41) get dropped at the RG. For early V6 users this was a major disappointment since it eliminated our Hurricane Electric 6in4 tunnels. The workaround I chose was to invest in static IPs, costing about 15 dollars per month. This upgrade had two benefits: 1) Bridge mode became unnecessary, giving me five static IPs. 2) The NAT/FW session table was resolved, so traffic bypasses it and goes straight to my firewall (Ubiquiti USG). This lets me continue working without affecting the main network, which is ideal when family depends on it.
I discovered that the BGW210 enables assigning static IPs to downstream devices without needing a dedicated static service, as the assignment is handled through the device itself. This was necessary because the BGW attempted to block all DNS queries from my Meraki MX firewall when I used it a few months ago, whereas the same configuration worked with an ASA firewall. I haven’t explored 6to4 tunnels yet, so it’s unclear if they’d interfere with this arrangement and whether I’d need to purchase static addresses. On another point, AT&T’s IPv6 allocation seems restrictive—it reserves a /60 per customer but ignores PD requests outside of /64, requiring complex workarounds to assign multiple /64s across VLANs. In my setup, I had to modify three switch ports, route PDs through the firewall, and then forward them to the BGW210 to obtain the necessary blocks.
... Yes... ATT RG not my favorite by a looong shot. But... My choice.... ATT and their nonsense over fiber.... Or Wave, over coax. Ill take a lame Modem I can work around over a lame cable plant I can do nothing about.
