I’ve a deployment with a couple of 580 in HA, configured in bridge mode.
On the LAN there’s a Cisco ASA firewall with a DMZ where there’s a SMTP server.
The DMZ has a dedicated subnet, different from the Peplink one, so to make it reachable from Internet I’ve defined a static route with the ASA outside interface as gateway.
All is working well, from the Internet the DMZ is reachable and mail is delivered.
The problem is when I try to connect to the SMTP from the Peplink to send notifications. I could not manage to reach it.
I tried with a Ping from the Peplink to the SMTP Server address:
If I test from WAN1, I got a redirect from the Internet router and no more.
If I test from LAN, I got no response.
On the ASA log there’s no trace of packets from the Peplink.
Does the peplink use the Static Routes from his own traffic?
