Add profile for PostTV (LU)

[fabianishere]

This change adds a new profile for the IPTV provider PostTV from
Luxembourg. This provider requires additional firewall configuration.

See #86 (comment)
for more information.

Hi, It seems that you've used 10.20.30.40 as static IP for the profile. It must be exactly 10.10.10.10 for the static IP used for the non PPPoE device (here eth8.35). Maybe I've interpreted it wrong ;-) here in the code snippets

You can test it by changing it in /usr/lib/udm-iptv/profiles/posttv.profile and re-running the configuration.

Ok, I'll try it as is, and if it's not working I'll try it with the change and let you know in order to modify the profile ;-)

Oh, I see that there is something wrong: you're setting eth8 to 10.20.30. but it must be eth8.35 which needs to be set to the static IP address 10.10.10.10 NOT eth8 as eth8 is PPPoE and the IPTV request here has to be done without the PPPoE tag, that's why we figured out together that eth8.35 must be used (it's always 35 for PostTV).

@horolux Could you also try changing the following in /usr/lib/udm-iptv/profiles/posttv.profile:

- db_set udm-iptv/wan-interface "$RET"
+ db_set udm-iptv/wan-interface "$RET.35"

Hi, seems to work with these 2 modifications.

So there is a modification need for the profile to change the static IP to 10.10.10.10/24 and $RET to $RET.35

Also, the table on the mainpage shall point to an description concerning the needed FW rule to add in order to get it working.
The description is in the discussion concerning this topic.
