GTM and asymmetric routing
Hi guys,
I have a question, hope you can give me some help as usual 🙂
Situation:
I have a GTM configuration for only one DataCenter with two links connected to a firewall. Services are published over the two links but the firewall has problems routing traffic using the same link where traffic arrives
i.e. if we open a ssh session using a service on Link 1, the traffic goes back through link 2. If we try the same over link 2, it goes back over link 2, which doesn't breaks the session.
This happens when both links are UP.
LC/LTM could avoid this behavior using auto last-hop feature but it seems the firewall has issues with this thing. So i was wondering if I could create a config in GTM to resolve only DNS queries over link 2 and if it's not available, then resolve for link 1.
In LTM this could be solved by a Priority Group Activation but it is not available on GTM 😞
Any comment is really appreciated,
regards, hheredia
