Hi friends. I've been going around in circles with this one for a few days but I'm hoping someone will be able to tell me where I'm going wrong. I've provided a fairly basic overview but hopefully you'll come across this issue in your careers/experiences.
Company A and Company B need to be able to have two way communication with each other via a Cisco ASA firewall in an external Data Centre. We have an IPSEC tunnel between Company A and the ASA and another tunnel between Company B and the ASA. HQ also talks to the ASA. Encryption settings have been checked and verified at each point.
Company A can ping HQ & ASA. The ASA can ping Company B
Company B can ping HQ & ASA. The ASA can ping Company A
Company A can ping Company B
HQ can ping Company A & Company B
The problem is that Company B cannot ping Company A
I've checked the VPN settings (this can be provided) and all seems to be ok. Is there any bit of configuration on the Digirouter that would block VPN traffic. What seems to be happening is that Company B is sending traffic via the ASA but the Digirouter does not know how to handle it.
Any assistance would be greatly appreciated.
