I have an ASA 5520 that I have used for several years as my vpn endpoint for remote users and site to site. Using cisco vpn client on remote users, I can ping my dns servers by ip and name, I can ping certain server names by ip and by name but not all. For instance. I have forwarding zones on my dns server: companya.com, companyb.com, companyc.com from my remote user I can ping server.companya.com and server.companyb.com but can not ping server.companyc.com (however I can ping server.companyc.com by ip address) so it has to be a dns issue somewhere. Any suggestions? thank you in advance
