| + | ===== Solution ===== | ||
| + | ''IPAPPEND'' worked for me without any problems. Honestly, I do not understand how it works, but I am using ''IPAPPEND 3'' (because I have been told to use this option). | ||
| + | Unfortunately, the documentation related to IPAPPEND is quite hard to find. Any pointers on how exactly IPAPPEND works will be helpful.\\ | ||
| + | |||
| + | Small drawback of this solution is that, the DNS entry is not passed. So, I won't be able to use URL's and I have to stick to IP only. | ||
