BigBlueButton wants port 80 - but Apache is there - eth0:0 is helpful?

Hello there

As title says, BBB wants port 80, but I have apache there.

To my knowledge, I can have second ip to my ethcard.
Code:ifconfig
eth0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500
inet 192.168.10.40 netmask 255.255.255.0 broadcast 192.168.10.255

eth0:0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500
inet 192.168.10.141 netmask 255.255.255.0 broadcast 192.168.10.255It is OK for servers to listen on same port but in different (virtual) ip?

And now I have to reverse proxy from apache to BBB?

Like this
Code:<Location "bbb">
ProxyPass "http://192.168.10.141"
</Location>or better like this?
Code:<VirtualHost *:80>
ServerName bbb.domain.com
ProxyPass "http://192.168.10.141/"
</VirtualHost>
