Help me to find a Cisco VPN router

Question

Hello,
I recently bought a TP-LINK router in order to set up a local network connected to a foreign VPN server (which is supporting MS-CHAP v2 protocol).
I configured my router the following way: on the “WAN” screen of the menu « Network », I selected the “L2TP” option, introduced my username and my password, then selected the “Dynamic IP” option and finally introduced the VPN server e-mail address.
It worked but not perfectly: it was possible to access some web sites through the VPN server but with some other web sites it didn’t work. For these web sites, it is necessary to use a "Secret” code (I successfully accessed these web sites using my iPad with such a “Secret” code). Unfortunately it is not possible to introduce such a code in my router.
I am now trying to find a router that allows the introduction of such a “Secret” code. I found routers with the possibility of introducing a “Secret” code but with “Static IP” instead of “Dynamic IP” but I found none with the possibility of introducing a “Secret” code with “dynamic IP”.
Do you know of a Cisco router - reasonably priced - which could solve my problem? Thank you for the help.
Best regards,
Jacques.

Jacques,
To ensure I understand exactly what you are asking for, I would like to ask you a couple of questions please.
Are you looking to have the router act as a client to the remote VPN server or site-to-site?
Since you mentioned trying to add all the credentials and information to the WAN interface, it appears to be a client setup. I am setting up some routers in the lab to validate my findings. I would just like some clarification. Our routers do have the ability to allow for L2TP, PPTP, and IPSEC passthrough if the credentials could be applied to the clients. I look forward to your response so I can answer as accurate as possible. Meanwhile see below:
