We recently did an implementation of two SRX's in HA for two locations, SRX 1500 & 550. Were both devices link back to a Juniper core, where exceptions were made to allow traffic over the devices
An IPsec VPN was configured on both devices to allow for a service to run over the vpn, note the service is up and running and we have access to it using another vpn.
Configs in place for the VPN;
Static Routes- all route defined
The problem is that we're only able to access the application intermittently, based on whenever it feels like working. Is there anything that's known to cause an issue within the configurations. I would really like to give more information but I can't.
