Hey everybody,

this is a follow up to FS#1501, Hans patched the Tunnel Encapsulation Limit since my ISP (UnityMedia Germany) doesn't support it - but now the IPv4 connection speed is drastically lower then the native ipv6 connection (4.64Mbit/s vs 120Mbit/s).
I have noticed that for some reason the automatically created wan6_4 interface is not a member of any firewall zone. Maybe the problem?

Hans was unable to reproduce the speed problems, I am willing to do some testing if directed. Since I am able to use my providers dual stack and lite tunnel as wished, I can compare speeds.

Supply the following if possible:

  • Device problem occurs on
    I am using a Linksys WRT 3200 ACM
  • Software versions of OpenWrt/LEDE release, packages, etc.
    latest official snapshot images and latest userland available
  • Steps to reproduce
    a cable network provider which offers ds-lite tunnels -> after installing snapshot and packages, remove the wan interface and reboot - dslite interface is automatically created by the dslite proto script -> (uci set network.wan6.encaplimit_dslite=ignore; uci commit; reboot) -> working ipv4 ds-lite tunnel -> speedtest plus general surfing experience outside of ipv6 capable networks are horrible

Best regards,
Tim
