Is there any experience of connecting a network drive via WebDAV to a router with dd-wrt?

Question

Network administration

Good day to all.
Interested in whether anyone connected a network drive via WebDAV to a router with dd-wrt. In particular, Yandex disk?
As I understand it, you need to install davfs2 to connect. It's not in the reps. Found some here -> wl500g-repo.googlecode.com/svn/ipkg/openwrt/davfs2... , but when executing

/opt/bin/ipkg-opt install /opt/share/davfs2_1.4.7-2_entware.ipk

writes

Clearing state_want and state_flag for pkg=davfs2 (arch_priority=0 flag=16 want=2)
Nothing to be done
An error ocurred, return value: 4.
Collected errors:
Cannot find package davfs2.
Check the spelling or perhaps run 'ipkg update'

Tell me where to dig?
PS The patient, for now, is an old man dlink dir-320.
