pfatt and 20.7 don't seem to work

[lrosenman]

Last week even my 20.1 system stopped getting DHCP from ATT, so I took the OPNatt stuff out and am NOT bypassing the RG at the moment.  If we find a way to get it to work on 20.7 (I upgraded since opnatt wasn't working anyway).

I did lose IPv6 as I can't seem to convince dhcp6c et al to get the PD from the NVG599.

I'll attach the opnatt.sh script I was running on 20.1.9 before ATT (AFAIK) broke it.

let me know what else I can supply.

Here's the original pfatt.sh script (not the newer one) if anyone wants to try this with 20.7

As usual you have to provide values for ONT_IF, RG_IF and RG_ETHER_ADDR should be set to the ATT RG mac

For what it's worth, I just upgraded to 20.7, and I still seem to be able to get DHCP from ATT using the traditional bypass. I've compared my pfatt.sh to opnatt.sh and they're mostly identical.

I do have a few extra parameters on the ifconfigs to make the interfaces promiscuous, but I wouldn't have thought that they should matter:

/sbin/ifconfig $RG_IF promisc -tso4 -tso6 -vlanhwtso
/sbin/ifconfig $ONT_IF promisc -tso4 -tso6 -vlanhwtso

A quick addition: one thing that broke for me recently on reboot was IPS. I was able to get IPS running some time ago, but after a power outage a week ago, my system would no longer maintain connectivity. It would come up just fine, but lose connectivity after a short time (less than a minute). I think that the netmap configuration for IPS somehow conflicts with the netgraph configuration for the bypass. Turning off intrusion detection fixed the problem. I haven't looked for a solution to have both work.

The original script also has promiscuous mode enabled on the RG and ONT

Code Select Expand

    echo -n "$(getTimestamp) enabling promiscuous mode on $RG_IF... "
    /sbin/ifconfig $RG_IF promisc
    echo "OK!"

    echo -n "$(getTimestamp) enabling promiscuous mode on $ONT_IF... "
    /sbin/ifconfig $ONT_IF promisc
    echo "OK!"

The only additional parameters are for TSO. The -tso4/-tso6 disables TSO for IPv4 and v6. And the -vlanhwtso disables TSO on VLAN. That really shouldn't affect anything ...

Has anyone that had their setup break with the update been able to confirm a workaround or cause for this?

I just upgraded from 20.1 to 20.7.

I'm using the original pfatt.sh from aus. So far, so good. I don't know if that's because I'm already authed, but I haven't had any troubles yet. If the internet is still up tomorrow, I can assume it works fine?

Everything came up, the interfaces remain the same, I have ipv4, but not ipv6. Hopefully that's not the start of something bad...
