26-6527-9 Alc-Primary-Dns The IPv4 DNS server address to be assigned to an IKEv1/v2 remote-access
tunnel client via configuration payload: INTERNAL_IP4_DNS. In case of
IKEv2, up to four DNS server addresses can be returned to a client, including
Alc-Primary-Dns, Alc-Secondary-Dns, Alc-Ipv6-Primary-Dns and Alc-Ipv6-
Secondary-Dns.
26-6527-10 Alc-Secondary-Dns The IPv4 DNS server address to be assigned to an IKEv2 remote-access

26-6527-61 Alc-IPsec-Serv-Id IPSec private service id, used by IKEv1/v2 remote-access tunnel, referring to
the preconfigured VPRN where the IPSec tunnel terminates (configure

attribute is omitted (configure service vprn interface sap ipsec-gw default-
secure-service). If the returned service id doesn't exist/out-of limits or exists
but not a VPRN service, the tunnel setup will fail.
