Is it possible with DD-WRT to setup a Port Forward rule and restrict it so it is accessible from only one outside IP? I've done this both on expensive PIX firewalls with Cisco IOS, and I've also done this on a cheap ActionTec DSL router from Qwest. However, with DD-WRT on my Linksys WRT54G/GL/GS there seems to me to be no such feature.
Can someone tell me if this is possible with DD-WRT on my Linksys WRT54G/GL/GS (DD-WRT v23 SP2 (09/15/06) std - build 3932)???

Just to clarify... I want to be able to access my home network from the outside IP of the firewall at my office, but I don't want my home gateway to respond to any other IP on the internet. Is there any way to do this with DD-WRT?

There has been a topic on this forum about adding a gui interface for this, but sofar it's not (yet?) implemented. You can use iptables for this, for the syntaxis you need, google for "iptables" and create the rule you want, then save it to the firewall (under administration -> commands). _________________ EA6900 DD-WRT v3.0-r48305 std

Indeed, I've requested it but havn't gotten a response yet. I'll add a request to the bugtracker for that. _________________ Firmware: DD-WRT v24-sp2 (latest available) mega

I discussed this feature (allow external access by IP and/or MAC... IPs change) with BS back in Feb. 2005 & his stated intent was to implement it when time allowed. Sadly, there was not enough interest, OR it just got lost in the sheer volume of feature requests since. In light of how this wonderful FW has progressed in that time, I can't fault the developers in any way, shape, or form, but perhaps with this renewed interest... _________________ NetGear XR500 - FW Version: DD-WRT v3.0-r55819 std (04/17/24)

@d00zah; yes let's hope that. Cause I would like this feature instead of doing it by hand with iptables. _________________ Firmware: DD-WRT v24-sp2 (latest available) mega
