Hardware and Performance / Re: Hardware for symmetrical 1Gb PPPoE connection?

« on: March 19, 2023, 06:49:11 pm »

I just got a Dell Wyse 5070 Extended with a Intel Pentium Silver J5005 off ebay for this purpose. I'm using it with a 4-port i350 card. It can get very close to line rate with a basic ruleset. There is a fair bit of variance in my testing, almost certainly due to the ISP.

Hardware and Performance / Re: CPU recommendations for 1Gbps w/PPPoE

« on: March 08, 2022, 11:03:02 pm »

One data point:

I have an HP T620 Plus with a 4-port Intel Ethernet card.

The CPU is an AMD GA-420CA, which is a lowish power (20W) 4-core 2GHz CPU. This CPU has a single-threaded passmark score of 667.

I get ~720down 750up over my CenturyLink Fiber (Gigabit Fiber with PPPoE) using OPNsense 22.1.2_1-amd64.
net.isr.dispatch = deferred
net.isr.maxthreads = 4

If I add - net.isr.bindthreads = 1, download drops and upload improves (610d/850u), it doesn't seem to make a difference whether I set maxthreads to -1 or 4.

One CPU core is saturated during the tests.

I figure I need at least 50% better single core performance to max out my connection. The Pentium J5005 mentioned above is in that ballpark, as is the Celeron J4105. I'd feel better with something that has at least 2x the single threaded performance.

19.7 Legacy Series / Re: 6rd status in 19.7?

I'm not sure if this is the same problem I have, but my work around was switching to a fresh install of the current version of PFSense.

Switching to a fresh install PFsense solved my problem, though I'd prefer OpnSense's much more coherent web UI (and available wireguard package)

19.7 Legacy Series / IPv6 via 6rd on Centurylink problem: No route to host.

« on: October 26, 2019, 09:09:11 pm »

I've recently switched to OPNsense from OpenWRT as part of a switch from Comcast to CenturyLink.

I'm having trouble getting IPv6 (via 6rd) working on OPNsense 19.7_5 and I could use some help.

The problem:

• I can't reach (HTTP, ping, traceroute) any IPv6 hosts beyond the OPNsense firewall/gateway from either clients, or the OPNsense box itself.
• I can resolve IPv6 addresses for sites like Google.
• Pings from client and OPNsense die with "no route to host"
• Traceroutes from clients report one hop, the opnsense box, before complaining there is no route to host on the next hop.
• Traceroutes from the opnsense box complain "no route to host"

My configuration:

• I have a VLAN interface setup on the ethernet port connected to the CL ONT, which is a necessary part of bypassing the modem they provided.
• I have my WAN interface configured to use a PPPoE tunnel for IPv4 and a 6rd tunnel for IPv6.
• The PPPoE section is configured with the ISP login info.
• The 6rd section is configured with the 6rd tunnel config info from the ISP (details below).
• I've updated the automatically created Point-to-Point device to use the VLAN interface for the link interface.
• The LAN interface is configured with a static address for the IPv4 configuration type, and "Track Interface" for the IPv6 configuration type.
• The Track IPv6 section is set to use the WAN interface as the IPv6 Interface (WAN is the only available option). The IPv6 prefix ID is 0x0, which is what it defaulted to.
• I have also chosen to allow manual adjustment of DHCPv6and Router Advertisements because if I didn't LAN clients weren't aware of a gateway on the LAN, and traceroutes failed immediately, complaining of no route to host.
• Router advertisements are currently set to "Assisted"
• I'm using default/autogenerated firewall rules for both IPv4 and IPv6 (includes "default allow LAN IPv6 to any rule")
• Firewall:Settings:Advanced AllowIPv6 is checked
• System:Settings:General Prefer to use IPv4 even if IPv6 is available is unchecked
• I'm using autogenerated gateways (WAN_6rd, WAN_PPPOE). "Under System:Gateways:Single," a gateway address is listed for WAN_PPPOE but not for, WAN_6RD.

Further Details:

• IPv4 works as expected
• Clients obtain IPv6 addresses within the Centurylink Prefix

That's all I can think of, now. I'll update if I think of anything else.

Suggestions on how I can get this working, or how to troubleshoot it further?

Thanks!
