This depends of your modem/router/firewall. I cannot help you for that sorry :S

Otherwise, you can also rent a small digital ocean VPS like a 10$/month droplet, install ubuntu (automatically done), install anoncoin following https://wiki.anoncoin.net/How_to_build_Anoncoin_from_source#Ubuntu_64_bit_or_Debian_8 , synchronize with the bootstrap.dat and configure correctly the anoncoin.conf in ~/.anoncoin
If you want to be a node for the i2p network you can also install i2p or i2pd and configure the anoncoin.conf in mixed mode (commented #onlynet=i2p and all others #onlynet= , and [i2p.options] enabled=1). It is better to not be in onlynet=i2p if you want to mine on this node because of an increase in stale blocks (although this is possible you will lose a small part of mined blocks due to increased propagation time, thereby reducing your mining efficiency).

Hope it helps and thank you to strengthen the Anoncoin network (especially if you happen to mine TX)!
