Dynamic Gateway support?

[Toxicman]

Hello, I have 3com OfficeConnect Router 3CR858-91.



Connection setup through PPTP.



My problem is, the ISP uses dynamic gateway IP (like vpn.corbina.net and switches the IP from time to time)



3com router doesnt support dynamic gateway from what i found, cause after setting it to domain name instead of IP it keeps rebooting untill i set factory defaults again.



Only way i get it work, use dynamic IP connection, ping vpn.corbina.net then enter the IP to router settings for PPTP. But the IP changes, so i gotto do that once in a while :(



It worked fine on D-Link routers (cheap ones), so there should be a way 3com can make it work too.



Is there any work around for this other than manual editing IPs? Or any hotfix?



Thanks in advance!



P.S. I have the latest firmware installed ofc :
