dual wan with lan ipv4 and wan ipv4+ipv6

[snoopy78]

Hi @all,

i've a quick question, where i'd like to get your opinion and some tips.

Currently i do have a leased line IPv4 only and my clients within my vlans are IPv4 only (some don't even support IPv6).
Now i'm thinking of getting a 2nd wan connection and do some load balancing.
The new ISP i'm thinking of, however, only provides IPv6 addresses.

What could i do? I need to keep my private IPv4 addresses for at least 10 devices, while the other could do IPv6.
