RED15 Stopped Working in Transparent/Split Mode

Oz Group

Hello,

Pretty much out of the blue I can't get my RED15's to work in Transparent/Split mode against 18.0.5 MR-5.

By work I mean accessing resources on the LAN behind the XG firewall.

I can't recall making any changes that will have any influence.

- All working OK with both Standard/unified and Standard/split.

- All working OK with both unified and normal firmware.

- All working OK with tunnel compression both on and off.

- All working OK with RED on LAN zone or separate zone.

- Checked with 3 different RED devices.

To make clear - using Transparent/Split mode, it doesn't work, regardless of other options (firmware/tunnel compression).

The tunnel looks as if it's working on both the RED and the XG side, but pinging whatever on the XG LAN doesn't work.

 

Thanks in advance, Adam.

    OK, I found the problem.

    If I set a second IP for the firewall (in either Failover or Load Balancing mode), it stops working.

    Even deleting the second IP and restoring the RED configuration to a single IP address won't work.

    As soon as I delete the RED completely and re-adding with a single IP, everything works.

    * EDIT *

    It seems to be a specific case to a larger problem.

    Any change I make after the initial RED configuration seems to cause the same issue.

    For example:

    I configured the RED to a separate zone - working.

    Changed to LAN - not working.

    Restoring to original zone - not working.

    Also vice versa with the same result - only deleting and re-adding makes it work again.

    The same problem here. It happens with any version xg 18.

    Although apparently everything is ok, the traffic between the sites does not pass.


    It also gives problems with site-to-site IPSEC VPN tunnels. I don't know if it's related to NAT.

    I can ping from UTM to the remote site, but from LAN to remote and from remote to LAN does not work.

    Were you able to resolve it definitively?

    As the RED's are deployed in remote sites I do not have constant access to, I decided not to make any changes to the initial configuration.

    That is, I hope everything will continue to work as long as I don't make changes...

    So to answer your question, once I realized this "workaround" I pretty much stopped there at the moment.
