Hi,
Station Pseudo-bridge usually won't work if you have r/stp active on the interface.
Not sure if it needs to be just disabled on one side or both sides.
Yes, I think so.I'll likely need to add more routing rules to tell the IP space to follow the other path if needed if I'm understanding correctly.
I am add address 192.168.4.4 on sub router,and on sub router set 192.168.5.4 dnat to 192.168.4.4
Sorry, I don't know.Isn't there any chance to get this working via dynamic routing protocols?
I don't currently need to know this, but I would like to for if/when I do need it (please)I was able to figure it out so I'm all set.
Ignore this, mine seems to handle this fine.
Another possibility:
Some special handling may be required if you have multiple public ip addresses on the router.
