VLAN의 DHCP 주소를 어떻게 검색합니까?

배경: 프랑스 ISP(Orange Fiber)에서 제공한 라우터가 형편없었고 몇 년 전에 Ubiquity ER-4로 교체했습니다. 이제 Debian 10과 systemd-networkd.

라우터의 공용 IP를 검색하려면 특정 VLAN 태그가 포함된 DHCP 요청을 보내야 합니다. 내 설정은 다음과 같습니다. 몇 시간 동안 IP를 얻으려고 노력했지만 DHCP 호출이 완료되지 않습니다(응답 없음). 문제 중 하나는 90DHCP 호출의 일부로 사용해야 하는 옵션의 형식일 수 있지만 먼저 VLAN에 대한 IP를 얻는 일반적인 방법이 올바른지 확인하고 싶습니다.

먼저 파일에 VLAN을 정의합니다 .netdev.

[NetDev]
Name=orange.832
Kind=vlan

[VLAN]
Id=832

그런 다음 이 VLAN을 파일의 인터페이스에 삽입했습니다 .network.

[Match]
Name=enp2s0
Type=ether

[Network]
Description=ethernet interface with VLAN attached
VLAN=orange.832

# In case of 'tagged only' setups, you probably don't need any IP
# configuration on the link without VLAN (or: default VLAN).
# For that just omit an [Address] section and disable all the
# autoconfiguration magic like this:
LinkLocalAddressing=no
LLDP=no
EmitLLDP=no
IPv6AcceptRA=no
IPv6SendRA=no

.network마지막으로 DHCP를 통해 IP 주소를 검색하도록 VLAN(파일을 통해)을 구성합니다 .

[Match]
# matches the VLAN on enp2s0
Name=orange.832

[Network]
Description=orange internet
DHCP=ipv4
#KeepConfiguration=dhcp
IPForward=yes

[DHCPv4]
#SendRelease=false
VendorClassIdentifier=sagem
UserClass=FSVDSL_livebox.Internet.softathome.Livebox3
UseHostname=no
# below is the authentication string which I have a hard time setting but it is completely specific to Orange in France
SendOption=90:string:\x00\x00\x00\....

[Link]
RequiredForOnline=yes

내 방화벽은 현재 완전히 열려 있습니다( /etc/nftables.conf).

#!/usr/sbin/nft -f

 flush ruleset

 table inet filter {
    chain input {
        type filter hook input priority 0;
    }
    chain forward {
        type filter hook forward priority 0;
    }
    chain output {
        type filter hook output priority 0;
    }
 }

이 설정이 합리적으로 보입니까? (즉, 이것이 systemd-networkdVLAN IP 검색을 설정하는 올바른 방법입니까?)

약간 우려되는 점 중 하나는 링크에 VLAN에 대한 언급이 없다는 것입니다.
