Hello to everyone,
yestarday I was at my friends house to fix his WAN connection. His router is running on the 7.4.1 version.
The original commands used to configure the WAN IP address and static route were like this: Notice the wrong netmask!

I am trying to recall what I saw yesterday, but the otput of the configuration must have looked like this: I have immediately noticed the dynamic route with the 0 IP address and /32 netmask, which didn't look right to me.
I was able to fix it by changing the Network IP to .1 The configuration now looks like this and everything seems to work flawlesly:

Originally I wanted to ask if there was some change in v7 routing configuration, but then I have compared it with my config and found out, that the proper solution would have been to change the Netmask of the WAN IP address to /24.

So my questions now are:
How come that everything is working?
Will it survive a reboot? I forgot to test it yesterday

thanks for any comments

PS: my intention is to set the proper IP addres netmask and network IP next time I come by physically. I am afraid to touch it via remote connection.

It works, because you created point to point config. If you have address with /32 mask, then the network parameter is remote address, which can be completely unrelated. You can have e.g.:
and in you connect it to another router with same config, only with swapped address and network parameters, it will work. It's less known, but same thing works also with Linux:
or Windows:
and possibly other systems too. It's perfectly valid configuration and doesn't cause any problems, as long as you don't need to access any other 192.168.88.x, because now you don't have route to that.

If you want to change it to /24, which is probably still good idea, to avoid confusing someone else in the future, it should be safe to do remotely, especially if you use Safe Mode.
