We have just installed a new PepLink Balance 30. Our configuration used to be inbound ADSL (fixed IP) to a Cisco UCS. This supported inbound VoIP, IPSec VPN (via port forwarding rules on the ADSL modem/router), and outbound Internet access.
We got a second Internet link (different ISP, Cable modem) and would like to setup the full load balancing, failover, etc.
I have the PepLink currently connected to the cable modem via WAN2 and into the LAN. The PepLink is at LAN IP .1 and I plan to use it as the default gateway for all network traffic. I duplicated the port forwarding rules and currently I can RDP in from outside, but not do a IPSec connection.
While I recognize that I have not yet re-configured the Cisco for its default gateway via the PepLink, it shoudl recognize the port forward as coming from a “local” point and reply via that same IP.
IO am wondering whether I also need to make any modifications to the IPSec VPN under Interfaces or should my port-forwards alone be ok?
