Topic: opening specific ports

[Brian Dall]

I recently started a new position, and the company has a VPN client that I'm not used to installed on the laptop they supplied.

Specifically in the company VPN user guide it says that the VPN software requires that a remote firewall must allow traffic to pass in both directions between the company's VPN server and the laptop on UDP port 500 and TCP port 50.

Can anyone tell me how I can open up or forward these ports on my home E-Smith firewall in a safe and convenient manner?  A script to open and close (or start and stop forwarding) the ports would be great, but I'd be happy with any useful information.  

I've read the Howto docs on IPCHAINS and forwarding and MASQ, but I'm not sure of the best way to proceed at this point.  I'm also not sure if the E-Smith configuration adds any twists to generic Linux procedures that would normally be used.

Thanks,

Brian

I seem to have found the answer already.  It appears it is an IPSec client and someone (THANK YOU!!) posted a great answer on how to allow IPSec clients to connect through at

It seems to be working just fine for me.  If there are any follow up issues with this fix, please let me know, however . . .

Thanks
