Yep, but not Ascends ;)

You probably wanted to write "LAN Adrs=62.152.25.1/24" or such. I don't
know whether the other routers receiving this route trash it due to
obscurity, but I could imagine so. Usually this works (gosh, I have had
setups running this way for weeks until I discovered the typo ;), but
I would not bet on it. If you give LAN Adrs a more sense value it will
either still not work or the problem disappears. If it still doesn't
work we should investigate further. BTW, if you really need transfer
nets, the profiles IP Options has entries for this, if you fill in
LAN Adrs it wants you to enter the address of the remote router in the
remote LAN, as always with Point-To-Point interfaces. This is not
exactly the same as unnumbered (your setup looks like a try to configure
unnumbered).
