[KPN glas] IPv6 icm Cisco ASA 5506-X

[s.vanrossem]

Hoi,

Ik ben een beetje aan het stoeien met mijn ASA-5506-X om IPv6 werkend te krijgen op mijn LAN. Mijn ASA is uitgerust met ASA software 9.9.2 en ASDM 7.12.2.
Inmiddels heb ik het voor elkaar dat de hosts achter mijn LAN-interface dmv LL een IPv6 adres krijgen via DHCP. Echter krijg ik de route naar buiten niet een de gang lijkt het.

WAN interface

code:

WAN is up, line protocol is up
  IPv6 is enabled, link-local address is fe80::2a6:caff:fe07:6e48  
  No global unicast address is configured

  Joined group address(es):
    ff02::1:ff07:6e48
    ff02::2
    ff02::1
  ICMP error messages limited to one every 100 milliseconds
  ICMP redirects are enabled
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  ND advertised reachable time is 0 milliseconds
  ND advertised retransmit interval is 1000 milliseconds
  ND router advertisements are sent every 200 seconds
  ND router advertisements live for 1800 seconds
  Hosts use DHCP to obtain routable addresses.
  Hosts use DHCP to obtain other configuration.

code:

show ipv6 dhcp interface WAN

Geeft niets

Op mijn host via de LAN-interface

code:

eno1: Router Advertisement from fe80::1:1
eno1: adding address 2a02:a456:xxxx:1:f8ee:e583:18c8:b320/64
eno1: adding route to 2a02:a456:xxxx:1::/64
eno1: adding default route via fe80::1:1

Iemand ervaring mee?

@s.vanrossem je openingspost is momenteel een beetje aan de karige kant, er ontbreekt namelijk een hoop informatie. Zou je eens willen toevoegen wat je nu allemaal hebt ingesteld en wat je al gevonden en geprobeerd hebt?

Op die manier kunnen we je een stuk beter helpen.

De config op de asa zelf:



code:

interface GigabitEthernet1/1
 nameif WAN
 security-level 0
 pppoe client vpdn group KPN
 ip address pppoe 
 ipv6 address autoconfig
 ipv6 enable
!
interface GigabitEthernet1/2
 nameif LAN
 security-level 100
 ip address 10.0.1.254 255.255.255.0 
 ipv6 address fe80::1:1 link-local
 ipv6 address 2a02:a456:xxxx:1::/64 eui-64
 ipv6 address autoconfig default trust dhcp
 ipv6 address dhcp
 ipv6 enable
 ipv6 nd ra-interval 60
 ipv6 nd managed-config-flag

Goedenavond.
Krijg je op dit moment een ipv6 op je outside interface? Bied KPN deze überhaupt op je verbinding?

[s.vanrossem]

@YoeriOppelaar op de asa krijg ik het niet voor elkaar.
Momenteel heb ik een pfsense machine schaduw draaien waarbij ik het wel voor elkaar heb gekregen dmv deze guide; Venxblog: KPN glasvezel via PFSense . Daar krijg ik netjes aan gateway en kan ik mijn lan interfaces en hosts daaronder voorzien van een /64 adres via dhcp. Met deze configuratie haal ik een 10/10 bij test-ipv6.com.

[YoeriOppelaar]

Hallo s.vanrossem,
sorry voor het laat reageren, paar dagen voor een project offline geweest.

heb je voor mij de output van de complete config (let uiteraard even op de persoonlijke dingen als omschrijvingen en zo, die mogen er uiteraard uit), en de output van "show ipv6 interface ..." en "show ipv6 route"

Hoi,
Ik zie nergens dat je een global unicast address krijgt? kreeg je deze op de PFsense wel?

[s.vanrossem]

Klopt, dat heeft te maken met RFC5072, IPv6 via PPPoe. Een ASA zou dat niet ondersteunen. Enig idee?

[YoeriOppelaar]

Dat heb ik me inderdaad niet gerealiseerd, KPN doet natuurlijk PPP.
Dan ben ik bang dat je zonder een router die de ppp op IPv4 en IPv6 ondersteunt, dit niet werkend gaat krijgen.
