Router & IPtables

[joclark]

Question(s) for those with web-hosting experience. I currently use a hardware router (Neptopia R-9100), have ports 22 and 80 open. As most do, I recieve nightly attempts to access/hack the server on SSH. One question is, do I need to utilize IPtables in addition to the hardware router for added security, or would this just end up being redundant?

Second question, I did set up IPtables (I'm admittedly very new to LINUX), not hard once you get into it, works really well!!
I see some interesting threads to limit SSH hits via IPtables. I have copied those lines to my tables, but no success. In all the instances I have found on the web, where you place them in IPtables is not explained. Because I couldn't see any good results limiting SSH attempts on my server, I have since disabled IPtables for now.

Do I open the SSH port first with an IPtables line - then place the access/login limiting lines before or afterwards? It seems to me if you first open port 22, that would that negate the additional lines afterwards, is my logic correct? Appreciate your ideas/suggestions.

Are there known routers which make poor firewalls, hopefully my Neptopia is not one of them...

Usually you put the limit statements in the same command statement (or command line) where you open the port. Do you have any examples of how you are using multiple commands to restrict access on port 22?

Thank you for your response. Here's the IPtables I tried:

sudo iptables -A INPUT -i eth0 -p tcp --dport 22 -m state --state NEW -m recent --set --name SSH
sudo iptables -A INPUT -i eth0 -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 8 --rttl --name SSH -j DROP

[kevdog]

Here is an example similar but not quite like yours:

iptables -A INPUT -i eth0 -p tcp --dport 22 -m state --state NEW -m recent --set --name SSH -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 22 -m recent --update --seconds 60 --hitcount 4 --rttl --name SSH -j DROP

[joclark]

Copied & pasted your IPtables, I give them a try. Thanks

[joclark]

It does not appear that the SSH rules is limiting attacks from the outside. I have copied & pasted my IPtables below along with a the
most recent attack:

As you can see login attempts are not being limited to a few/minute...any ideas?

[pløp]

An other way are to use fail2ban.

This daemon read your /var/log/auth.log, and block the IP who have try 3 times to open a SSH connection without success.

You can define how many retry, the lengh of the ban, whitelist IP, ...

By default I install fail2ban on the dedicated server of my customer. And it's work fine.

[Sporkman]

...or you can just change the ssh port from the default port 22 to another port (up in the 4 digits) - that should eliminate most of those attempts.
