DHCP on WAN VLAN 4 no longer offers router

[thmjanssen]

The update_iptv_route.sh script to update the routing on the USG for IPTV assumes DHCP on VLAN 4 offers a router. This is no longer the case on KPN's network (at least in my case).
By updating line 7 into this, it works again:

r_ip=$(cat /var/run/dhclient_eth0.4_lease | grep new_dhcp_server_identifier | awk -F= '{print $2}' | tr -d \');

Ran into the same issue, two things I noticed while debugging this:

• I think there's a typo in your snippet? I had to use eth2.4 instead of eth0.4 as there's no eth0.4 on my system?
• In my case, with the eth2.4, it returns the same IP address as listed in the original show dhcp client leases interface eth2.4 command under dhcp server

You have a USG Pro? On the USG 3P eth0 is the WAN interface.

I do indeed, thanks for clearing that up!

Please be aware that KPN officially recommends RFC 3442 implementation (dhcp exit hook that configured the static routes). If KPN changes this to something else then the DHCP server your setup will stop working.
