GSM Failover with IPv6
-
On mine I don't use IPv6 but I do see it in the log. You have specified on the OPT2 interface to use DHCP6 for IPv6 configuration type?
-
Yes, I have. I also noticed that MPD wasn't using my custom modem init string because the CGDCONT thingy uses quotes. Said quotes need to be escaped in order to work. That was keeping the modem from requesting the right PDP context. It now successfully sets IPV4V6, but MPD still won't configure the opt interface with an IPv6 address. I've definitively tried DHCPV6. Should that work? Somehow I thought MPD would use IPV6CP to set the interface's address, but still failed to enable that properly.
-
I guess there should be a PPP setting for the IPv6 address configuration of the interface, just like there is for IPv4, but there isn't.
-
I am not much help on these topics. I am wondering about your hardware. Did you have to change the PID or was it working OOB?
-
Maybe even try the "Track Interface" setting for IPv6
-
Tracking the interface will not do what I think it should do, as it would track another interface, not the WWAN interface itself. I'm using a genuine MC7355, with VID 1199, so no need to get the VID/PIDs changed and the card unlocked.
Here's some more logs from my attempt to configure IPv6 with MPD. Note that I had to change the modem init command in the advanced PPP settings to```
+CGDCONT=1,"IPV4V6","fast.t-mobile.com"There are 10 SendConfigReq, which all seem to time out and not get a response back. I've reached a bit of an impasse here, as I'm not sure how the peer is supposed to respond and whether the sequence is correct. The address 020d:b9ff:fe3a:496d is made up from my LAN interface's mac address. I think this is correct, as it is not specifying a desired prefix towards the peer, but rather just configuring the link address part of the IPv6 address.Dec 12 09:09:17 gw ppp: [opt2] IPV6CP: SendConfigReq #10

Sorry, I meant PID , So you bought a device with VID/PID of 1199/9041. That is what I was wondering. Yours is only the second mention I have heard of the device. The other user sounded like he had to switch his to PID=9041.
I recently setup MPD5 and I think it would benefit you to make this work in FreeBSD first and then it will be easy to backtrack to pfSense. Probably just a mpd.script setting it needs. Have you looked at the mpd5 doc's regarding ?
I don't know that I have ever seen anyone manipulate the modem init string that way. I knew it was possible. There are also mechanisms in the modem which make me wonder too. Have you had a good look at the Sierra pdf for Extended AT commands. It is pretty crazy all the options available. IPv6 might be one of them.
That said it might be easier to confirm with a Live Linux CD that IPv6 is working right at the modem level.
Once again I am sorry I can't help more.
-
One thing that comes to mind is this. I used Advanced PPP>Modem Init String> one time to make an Ericsson H5321 work. It involved simply adding CFUN=1 as init string. This AT command simply tells the modem to turn on, but what it was doing is bypassing part of the modem mpd5 script so that the modem would work. The default settings were not working correctly and this worked.
How does this relate to your case: Well notice there is no APN given in my example. The pfSense GUI settings for my APN sticks.
I wonder if your not trying to feed two set of settings to MPD5. One from the APN field in the pfSense GUI and one you are forcing with AT+CGDCONT and the init string. Can you not feed it just the IPv6 setting you need? -
Appreciate the responses, but I think my modem configuration is fine. I enabled some extended logging to verify the CHAT script and that looks good. My init goes through and isn't overridden by other commands. I know because if I change the PDP context to say "IPV6", I no longer get an IPv4 address. Also, yes, my device is VID 1199 and PID 9041. When the PDP is "IP" instead, the modem connects properly but only gets an IPv4 address, as expected for that PDP. So the problem just persist with IPV4V6, to get both an IPv4 and IPv6 link address. IPV6CP does not have any configuration options in MPD5, so there's not much I can tweak there. As you can see, the log above shows some rather verbose debugging output, including the whole wire payload to configure the link in IPV6CP's finite state machine.
However, after some consideration, I found a couple issues with my initial setup:
First, since the LAN interface tracks the WAN interface for its IPv6 address, whenever the main Cable route goes down the LAN interface will have an unroutable address, as well as the whole subnet which was configured by tracking the WAN interface and advertising the /56 subnet given to the WAN link. I have to figure out something around getting an ISP independent IPv6 subnet that can be routed across both links. A tunnel with HE.net would be nice, but they don't support dynamic tunnel end-point addresses, as far as I know. If anyone would have a suggestion around that, that would be great. And no, BGP with our own ASN is a bit out of the question. As for IPv4, given that it's doing NAT, the same issue does not exist and is working fine.
Secondly, for getting local DNS resolution to work, I realized that I didn't have a floating firewall rule for tcp/udp port 53 to enable policy based routing over the gateway group. Once I added that, my DNS resolutions started working again, albeit only over IPv4.
-
While researching another problem I found this command in the Sierra Extended AT Commands pdf and was thinking of you.
AT!CUSTOM="DHCP6ENABLE",1
You can run the command AT!CUSTOM? to show custom settings and AT!CUSTOM=? to show custom options.
-
Unfortunately, it doesn't look like my modem understands the DHCP6ENABLE option. Here's a list of valid options, as printed by AT!CUSTOM=?:
!CUSTOM: "ISVOICEN" "STKUIEN" "PCSCDISABLE" "CMCLIENT" "SIMHOTSWAPDIS" "ADBENABLE" "NOROAM" "GPIOSARENABLE" "GPSENABLE" "GPSLPM" "REL8FASTDORMDIS" "RRCREL7CAPDIS" "FASTENUMEN" "GPSSEL" "WAKEHOSTEN" "AUTONETWORKMODE" "WIN7MBOPTIONS" "NMEAENABLE" "CFUNPERSISTEN" "UBISTENABLE" "GOBIIMEN" "GMMCAUSE7REMAP" "GPSREFLOC" "SINGLEAPNSWITCH" "USBDMDISABLE" "SIMLPM" "USBSERIALENABLE" "CSVOICEREJECT" OK -
Do you know what firmware you are using. I don't think I saw a T-Mobile in the Sierra firmware package. Have your upgraded firmware at all? Maybe post your ATI command output and AT!UDINFO? Perhaps you have an older firmware..
I saw the command in the MC7700's list and looked it up in the pdf. I need to check again as maybe it is only Qualcom MDM9200 modems use that command.
-
Updated my device and have some more settings now.
