The file is too big, I only copy the the last 50% of it.
FYI, I only changed the interface name yestrday and it looks like this now: -

16F84 · August 5, 2021, 12:32pm

Do you have internet connectivity? Did your provider give you an AFTR address?

16F84 · August 5, 2021, 12:44pm

Shouldn't wan6 also have eth2 defined?

OR should it have defined an ifname?

config interface 'wan'
option ifname 'eth1'
option proto 'dhcp' #ignore

config interface 'wan6'
option ifname 'eth1'
option proto 'dhcpv6' #ignore

*TimB87:* Hey everybody, my provider forces me to use ds-lite to get connect…ion to the v4 internet. I first tried openwrt on an old Linksys E4200, which worked with any version - but the router ran with around 50% cpu utilization at all times and it was very slow. After updating to an Linksys WRT 3200 ACM, 17.01.4 works great! Newest trunk though doesn't. It also does not work on WRT 1900 ACS v2 and Netgear R7800 according to various forum posts. I already gathered some information about it on the openwrt Forum -> https://forum.openwrt.org/viewtopic.php?id=73755 What else can I provide to make future versions work? To mee, it seems like there is a problem with odhcp6c and maybe dnsmasq? Plus the script always produces "command not found" errors (even on the e4200), so maybe the script does not work flawlessly? Thanks for your help! Best regards, Tim

Which dnsmasq do you have installed?
What version of OpenWRT are you running?
What router are you using?

Ameen · August 5, 2021, 3:30pm

I must clarify that I am building the whole topology of DS-Lite in a testbed.
So, I am trying to build the below topology: -

I do have IPv4 connectivity through my eth0 (NAT) which sub-natted from my main host (my pc) NIC.
I am also building my own AFTR using OpenWrt, and I have the same issue there:-

Ameen · August 5, 2021, 3:33pm

There is no need, check the last line here: -

Ameen · August 5, 2021, 3:36pm

The whole topology is built using vmware VMs, as explained here: -

Below is the system overview: -

16F84 · August 5, 2021, 8:58pm

What NIC? Swap NICs?

https://kb.vmware.com/s/article/1034782

Swap PCs? Swap CPUs?

https://www.vmware.com/resources/compatibility/search.php?deviceCategory=cpu

All patched up? What rev?

Ameen · August 6, 2021, 4:11pm

I don't know if we are on the same page.
I am connected to my ISP though my home router, which has the address is 192.168.0.1
I am connecting to it through my PC, I am using VMware workstation hyperviser upon my pc.
So, I am using a different VM network, like connection from the host to the B4 in vmnet 11, connection between b4 and AFTR in vmnet12, etc.
Every topology element has eth0 with as nat interface with 192.168.172.2 gateway.
As for the error I am seeing in Luci interface, Am I supposed to see DS-Lite as a seperate network device when I type "ip add" command in CLI ??

16F84 · August 6, 2021, 10:31pm

I don't know if your VM hardware is compatible with the recommended hardware list.

"Also note that dslite doesn't support ipaddr or netmask parameters since
RFC6333 specifies fixed IPv4 addresses so these parameters do nothing." Quoted from the link below:

https://openwrt-devel.openwrt.narkive.com/aKljOoKw/ds-lite-interface-is-not-coming-up

I have seen other recommendations like using a known good router that supports Ds-lite to verify the ISP is supporting it - ie. the ISP provided router.

If that works then see if you can get an openWRT based router to connect and then refer to the network settings used as a guide for your VM.

If you are trying to make your own B4 and AFTR try doing it first with a couple of older inexpensive routers (using openWRT) from some of the openWRT guides (or search the forums) so you know they will work. Then use those configs as guidelines.

HTH

??? It doesn't look like it auto configured correctly. Manually add it?

Ameen · August 8, 2021, 11:05am

Wan6-ds-lite interface is being tunneled using 'wan'.
In 'wan' interface there is eth2 device configured.
So that should do the trick.
I tried to add 'eth2' device in 'wan6', it didn't change anything either.

Thanks for your support anyway man.

Make sure that IPv6 gateway is set on inteface wan.

Here are some useful notes I got while I was strugged with this issue.

Error: Network device is not present seems to come from dslite.sh.

See: https://github.com/openwrt/openwrt/blob/1e4469b090a7e3234345c1b7f17c956ec7dc0b81/package/network/ipv6/ds-lite/files/dslite.sh#L27

This file is deployed at /lib/netifd/proto/dslite.sh inside openwrt.

In some cases proto_add_host_dependency will return exit code 4 (UBUS_STATUS_NOT_FOUND).
And shell script seems to be terminated then.

We can observe this behavior by modifying shell script like following:

	( proto_add_host_dependency "$cfg" "::" "$tunlink" && logger ok || logger err $? )

Note that it needs restart of /sbin/netifd process, when we change dslite.sh and needs to reflected correctly.
This will help: service network restart

The log can be seen from either:

OpenWrt: Status → System Log
Shell: logread | grep "user.notice root:"

proto_add_host_dependency seems to be used to propagate ifdown/up events coming from underlying iface (like wan).
e.g. whenever wan is restarted, dslite is also restarted.

See also: https://openwrt.org/docs/guide-developer/network-scripting

	( proto_add_host_dependency "$cfg" "::" "$tunlink" )

The 2nd arg "::" seems to indicate "find the interface having IPv6 default gateway".

Although dslite is usually activated on valid IPv6 enabled network, sometimes we build easy sandbox for testing purpose.

Thus changing from "::" to "" will skip checking of default gateway.
