Hi,
I am trying to have connected my two UTMs (9.315-2) via a RED tunnel, using the same subnet 192.168.0.0 / 24 and bridging.
After having spent several hours and red every thread i found in relation to that I am giving up an asking for help.
What I have is:
- working red tunnel between UMT MUC (IP 1) and UTM NYC (IP 2)
- LANs connected to each UTM with same above subnet 192.168.0.0 / 24, but different gateways (IP 1 / IP 2, see above), no conflicting IPs.
- both UMTs do DHCP for non conflicting ranges within the same subnet.
- a bridged internal interface with reds1 / redc1 on each side
- a firewall rule on each side internal -> all -> internal -> allow
- NO masquerading rule internal - internal (but had tried that too)
- Intrusion Prevention, Application Control Advanced Threat Protection are OFF.
Result / Status qou:
- working ping from each UTM to the other UTM
- UTM NYC can ping devices in the remote network but not the other way around (! even so i cannot find any relevant difference in configuration)
- no UTM connected network device can ping or TCP connect to devices behind the remote UTM
- not evidence of allowed or denied traffic in firewall logs
Is there anything else if have overseen or where i could start investigating any further ?
Thanks a lot for any hints in advance. [:)]
