Triode Spotify plugin problem with Squeezeplay on same computer as LMS

Hi,

I have the LMS server on my Linux laptop. I also have Squeezeplay client on the same laptop. And problem is that I'm not able play Spotify on that Squeezeplay (spotify plugin log: player address mismatch 10.0.1.118 192.168.128.1). Local files and netradio play fine.

Both of the above IP addresses are for the laptop. First one is given by DHCP from uplink network (eth0) and the second one is the fixed/static address of the bridge (br0) that I'm using to share the internet connection with ad-hoc WLAN (for example to Ipad). Spotify works for the other clients in both 10.0.1.0/24 and 192.168.128.0/24 networks. The only problem is the Squeezeplay on the same laptop as LMS. I'd want to use the static 192.168.128.1 address for laptop Squeezeplay because with that configuration the playback continues even if I lose the network connection.

How could I solve the Spotify plugin "player address mismatch"-problem? With iptables? The current iptables NAT configuration is really simple:
iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A POSTROUTING -t nat -j MASQUERADE -o eth0
iptables -A FORWARD -o eth0 -i br0 -m conntrack --ctstate NEW -j ACCEPT

Any advices?
