When I tried to enter some standard ipv6 things in "Additional pppd options" of the internet interface the wl500gx would no longer connect to internet. This was even the case when I entered the benign PPPD_EXTRA="".

Then looking in the source code for the firmware 1.9.2.7-7e I see that in the two places where HAVE_INET6=y appears it is commented out. Therefore, I assume that the currently installed ppp does not support ipv6.

I am hesitant to uncomment in these two places and recompile because I do not know what side effects there will be. For example, assuming that the recompilation works will the resulting firmware still fit in the wl500gx.

Any ideas will be appreciated.
Thanks
