I have a Linksys Wrt54gs with Firmware Version: v3.37.2 - HyperWRT 2.0b4 and when I try to port trigger a port such that it port forwards port 113 it doesn't work properly. I would port trigger a port such that it would port forward port 113 and send information from the triggered port and when I go to www.grc.com it shows port 113 is stealth. When I try to set the port forward port to any other port (after the same port trigger) it'll show the port as closed. I tried this with the, â€œFilter IDENT(Port 113)â€ both checked and unchecked (under security - firewall) and I would get the same results. For some strange reason, it appears port triggering / forwarding works for all other ports except port 113 (that is when I try to port forwards port 113 after port triggering another port it doesnâ€™t work).
