iptables issue

I have an old Sony Xperia E (C1505) smart phone that I decided I'm going to install Pirate Box on. Well, after rooting the device and a few other issues I had to work through, I am (I hope) close to getting it working. However, when I start Pirate Box it tells me 'Unsupported device! - Command "iptables" not found'.

I tried to install iptables through the play store, but the version I have is later than what is available (installed version: 1.4.11.1. Play store version: 1.4.10). Could this be the issue? If not, any other suggestions to help me over this last hurdle?

Thanks!

Yes, you can install it and check the latest firmware which has been developed by [errorcode0x.com] and also get technical assistance.
