Hi
I have a group of dynamic objects defined by FQDN in mulitple ASA 5506/8-X.
Somehow after ugrading ASA software from version 9.6(1) to anything later, the DNS resolver fails.
Same config, nothing changed.
My remote sites are doing IKEv2 site-to-site to HQ, with all RFC1918 addresses in crypto map acl.
Current ASA version, where this is failing: 9.8(1)
DNS config/status:
FW# sh run dns
dns domain-lookup inside
DNS server-group DefaultDNS
name-server x.y.z.w inside
name-server x.y.z.q inside
domain-name dom.local
FW# sh dns
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
Name: host.domain.tld (unable to resolve)
DNS servers are pingable sourcing the inside interface OK.
Anyone seeing the same issue?
Do you have a solution or workaround?
If I downgrade to ASA 9.6(1) DNS resolve start working immidiately.
Kind regards
Thomas Winther
