ACCEPT tcp -- wan_ip/wan_mask anywhere tcp dpt:ssh

before I manually ran the iptables, here is the output of "iptables -L"

DROP udp -- anywhere anywhere multiport dports 161,162
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:ssh
DROP udp -- anywhere anywhere udp dpt:tftp
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:ftp
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:www
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:telnet
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere multiple source IP: 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere multiple source IP: 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, state NEW tcp dpt:telnet
ACCEPT tcp -- wan_ip/wan_mask anywhere state NEW tcp dpt:www
ACCEPT icmp -- anywhere anywhere icmp fragmentation-needed
DROP icmp -f anywhere anywhere
DROP all -- anywhere anywhere

I think the problem here is DROP showed first and then ACCEPT,
I manually ran below
iptables -I INPUT -p tcp -s [wan_ip] --dport 22 -j ACCEPT

Now the out was
ACCEPT tcp -- wan_ip/wan_mask anywhere tcp dpt:ssh
DROP udp -- anywhere anywhere multiport dports 161,162
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:ssh
DROP udp -- anywhere anywhere udp dpt:tftp
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:ftp
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:www
DROP tcp -- anywhere anywhere multiple source IP (inv): 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, tcp dpt:telnet
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere multiple source IP: 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere multiple source IP: 192.168.1.29,wan_ip1,192.168.1.2,wan_ip2, state NEW tcp dpt:telnet
ACCEPT tcp -- wan_ip/wan_mask anywhere state NEW tcp dpt:www
ACCEPT icmp -- anywhere anywhere icmp fragmentation-needed
DROP icmp -f anywhere anywhere
DROP all -- anywhere anywhere

Now I am able to ssh from office into my home router, can anyone please kindly advise how to make this setting permanent?
I assume I need to write this into the bootloader environment variable? but question is how?

I checked /proc/sys/dev/adam2/environment but it doesn't contain the commands that tiepolo wrote

Thanks in advance.

note: I had already posted above once but I didn't see it, so I guess I forgot to submit, if I double post, whoever has access, please delete one of them.
