Advice required please.

This is following on from previous questions regarding the Security of my network.

Having just read these two posts, and having previously used a Draytek Routers and access points, I think I need to look into getting a better firewall device than the basic NAT firewall that the Deco XE75 provides, ie IP address filtering.

•   How secure is your network? (https://community.tp-link.com/en/home/stories/detail/255)

"........... A basic NAT firewall alone is not enough for today’s various hacker attacks and malware. Generally, a router is also equipped with a firewall feature that provides more sophisticated protection. An SPI firewall is one such feature....."

• Firewall: Guardian of Your Wi-Fi Network - (https://community.tp-link.com/en/home/stories/detail/255)

As the Deco does not provide IP Adress filtering,(re secure VOIP service), and as common advice is to not use the SIP ALG option where you can due to its vulnerabilities, the only option I have is standalone firewall. Buying a stand alone firewall, or a better router means I bought a 3 pack Deco unit by mistake and should have bought a 2 pack and router, done now moving on. I like to keep my tech to one brand this way I can avoid any incompatibility problems.

So what is the lease expensive TP-Link router I need to give me the firewall benefits I thought I was getting with my Deco system, or will this feature be included in the next software update, when/if ever it gets realeased

Cheers

 Tried to use link option but says I can not use external links - they are to the TP-Link Forum?
